View Data Sheet

Specifications

Using the 193-L, the eyepiece of an instrument may be reoriented into a right angle configuration. The 193-L eyepiece adapter swivels 360 degrees for ease of viewing from any angle. This allows the use of the instrument in obstructed or tight setups. It also allows for shots near zenith (straight up).

The 193-L adapter also allows for autocollimation through illumination of a reticle pattern on several of our transits and one of our levels. With it, you can collimate and colineate two instruments, or illuminate a model 188 autoreflection target mounted on the end of a telescope barrel.

The 193-L is interchangeable with the removable section of the main telescope tube on several of our transits and one of our levels. The unit comes complete with model 508 light source which operates on voltages from 110-220VAC.

The 193-L is installed by replacing the removable adapter tube on the ocular end of many of our telescopes. After installation, the 193-L may be swiveled to any angle around the main axis of the telescope.

Specifications

The 196-1 allows complete flexibility, combining the features of the previously offered 191 and 192 eyepiece units. A rotating filter disc provides five options: "see-through" capability, reticle projection, green-filtered light, beam splitter with no coating, beam splitter with partial coating. A built-in diffuser may be engaged for even light distribution over the entire field of view when autocollimating, collimating, or colineating. By removing the light source, the 196-1 operates as a fixed right angle eyepiece. The unit comes complete with model 508 light source.

Specifications

The 1241 combination eyepiece is interchangeable with the standard eyepiece of the K+E type telescope found on certain instruments. The eyepiece unit can be converted in the field as required to form a straight-through vision system or a right angle system. The 1241 includes a 508 light source which operates on voltages from 110-220VAC, 50-60 Hz.

Specifications

The 1260 is a right angle prismatic eyepiece adapter. It's great for use in very low setups, or when working close to walls, columns, or similar obstructions, when you can't get behind the normal eyepiece of the instrument. The 1260 may be rotated through 360°, giving an erect but reversed image.
