Specifications

The 2302 attachment fits over the objective end of our alignment telescopes and converts the instrument into an angle reading telescope. Normally, the micrometers on an alignment telescope allow you to measure the lateral displacement of the line of sight. But with this attachment in place, the micrometers read in arcseconds when the instrument is focused at infinity. In fact, they read directly to one arcsecond over a range of 50 arcseconds. This effectively converts the instrument into an autocollimator. Maximum usable distance for autocollimation is approximately 30’ (9.14 m). Infinity setting on focusing knob is approximately 17’ (5.18 m).

Specifications

The 8415SY Camera Kit is ideal for a number of applications, including tasks that are repetitive or long term in nature, remote monitoring, in classroom settings, or when you simply want to make telescope images easier to see and evaluate.

The kit consists of a Sony CCD camera power supply, 9" black & white monitor, and an adapter which allows the camera to be fitted to the eyepiece on any of our 2022 family of alignment telescopes.

The analog camera weighs only 60 grams, and features excellent vibration and shock characteristics. It has a 768 x 494 pixel output and a C-type lens mount.

When used with an infrared (IR) LED illuminator, this camera can capture images in very low light environments and/or easily detect features that are more distinguishable with IR illumination.

Specifications

The 186 multiple paired-line target is machine-engraved on white plastic laminate. This target may be slipped over the objective end of Brunson-style transits (or levels) and used for non-illuminated auto reflection at distances greater than ten feet. The target is adjustable to allow for centering on the optical axis of the transit. Orientation of the target with respect to the instrument's reticle is accomplished by detente positions fitting into the pin found on our telescope barrels.

Specifications

The model 188 is a multiple paired-line glass target used with transits or levels equipped for autocollimation (having a light source).

Slipped on the objective end of the instrument, it allows the setting of the telescope perpendicular to a mirror. Adjustments are provided to permit centering the target pattern on the optical axis of the transit (two opposing pairs of setscrews set at right angles allow you to adjust the position of the glass target).

Specifications

The 187-S was specifically designed for quick, precise leveling of alignment telescopes and collimators. It can also be used to level any cylindrical surface between 1¾" and 3" in diameter. Like many of our levels, both ends of the bubble are viewed simultaneously by using prisms and a magnification system. This "coincidence" or "split" bubble presentation ensures the most accurate reading of the position of the bubble (see sketch below). The bubble is conveniently viewed from any position via the 360-degree rotating turret assembly on top of the unit. The 187-S will indicate off-level conditions as small as one arcsecond. An elastic strap is included to secure the level to the instrument. The coincidence vial is supported by two hardened, ground, inverted "Vs" on a 5" center.

Specifications

The 3205 level is used to orient the reticle of our alignment telescopes and collimators vertically and horizontally. The cross level is positioned by means of a stud fitting into a hole in the barrel of the instrument tube. When the level bubble is centered, the crosshairs of the instrument will be vertical and horizontal. The level vial has a sensitivity of 90 arcseconds per 2 mm movement.

Specifications

These scales are used with our optical instruments to measure the precise distance of any object from the line of sight. Then, since the line of sight effectively establishes an extremely straight reference line, alignments between different objects (such as machine components, foundations, rollers, etc.) are quantifiable.

Our scales have optical targets evenly spaced every 0.100". The optical micrometer on an instrument works as a vernier, displacing the line of sight laterally. Using this displacement, the reticle is "brought into register" with the nearest target on the scale, and the precise displacement is read directly from the graduated micrometer drum. By adding or subtracting the micrometer's reading from the scale position, a precise measurement is made.

Specifications

Three-dimensional measurement systems employing theodolites or total stations often require an artifact of known length in order to calibrate the system prior to data collection. That's where the 564W-CE and 564W-CM come in. These artifacts may also be used for verification of system accuracy at various times during a "shoot". These special scales, when used with our Invar scale extension kits, provide the required calibration index for such systems. A bull's eye target with three consecutive circles is located on a white face scale at a precisely calibrated distance from the reference end of the scale. Two calibration scales are available.

The scales are made using the same process as our optical tooling scales. They have a hardened steel substrate, with black lettering on a matte white background and a non-glare topcoat.

The 564W-CE and 564W-CM are designed for use in pairs, with our calibration-grade Invar kits. The English unit kit is 803-C; the metric unit kit is the 803-MC. These kits include one fixed and one rotating scale holder so that the optical targets on each end can be oriented in the same direction.

Each scale is shipped in a vinyl sheath.

Specifications

The 562-A employs a high energy Neodymium magnet with approximately 15 pounds of pull to hold a scale firmly against any ferrous material, regardless of surface orientation. That means you can orient your scales pointing upward, downward, or sideways, should the situation call for it. Plus, a new design allows placement on rollers from 1.5" to 12.5" in diameter - both sides have angled cutouts. And magnet is strong enough to hold a scale horizontally on a ferrous roller.

The edges of the scale holder are precisely ground to 90° in order to assure that the scale is held perpendicular to the surface. The stainless steel magnet body won't corrode in harsh environments. The scale is captured between two parallel jaws. A thumbscrew moves one of the jaws, which squeezes the scale on its edges and holds it firmly in place. The jaw edges themselves are beveled, causing the back of the scale to be firmly seated against the scale holder as the jaws close. The 562-A will hold any of our currently-offered optical tooling scales up to and including the 20" size, as well as our older type scales (which were fabricated from a thicker material).

Specifications

The 562-41 is the larger, stronger magnetic holder needed for our 40" and 1000mm scales. It includes a plastic grip for easy handling, and has an eccentric-pivot lever which gives the user a cam action "lift" to gently remove the unit from any magnetic surface. The scale is captured on the faceplate by two dovetail brackets. One bracket is permanently mounted on the side, the other is secured and tightened by two knurled thumbscrews. If necessary, the entire faceplate pivots slightly to help you place the scale in an orientation which is approximately plumb to the mounting surface. Then, the third knurled thumbscrew fastens the faceplate in the desired orientation.

Specifications

The 562-VA helps you place a scale against many cylindrical drums or rolls, and hold the scale nominally on a diameter of the roll. The 562-VA set includes two scale holders: one 562-VA-120 V-block (120°), and one 562-VA-160 V-block (160°). One side of the V-block holds our 40" or 1000mm scales, and the other side holds all of our smaller scales (see photo below). Eyebolts allow the use of straps or tie-downs for extra security.

Note: The 562-VA is a set consisting of both V-blocks, but each V-block may also be purchased individually.

Specifications

The 563 and 563-40 levels are very handy tools which attach directly to your optical tooling scale, having two bull's eye vials mounted at right angles. This allows you to orient your scale either horizontally or vertically. The levels are sufficiently sensitive to allow you to keep any significant cosine error from creeping into your scale readings. A knurled thumbscrew tightens an angled dovetail bracket against the side of the scale, holding it firmly against the reference edge of the level. The scale levels may be placed at any convenient place along the length of the scale. The 563 fits any of our scales having a width of 1" - (3" to 20" and 80mm to 500mm scales). The 563-40 fits our 40" or 1000mm scales. It is identical to the 563 except for the addition of an extra spacer to accommodate the extra width of the 40" and 1000mm scales.
