522240 & 521241 Combination Eyepieces:

• The 522240 consists of a right angle eyepiece plus an illumination unit which can be used either to project an image of the reticle onto a target or for autocollimation.
• The 521241 is interchangeable with the standard eyepiece of the K&E type telescope found on certain instruments.
• Both can be converted in the field as required, to form a straight-through vision system or a right-angle system.

 

621871 Stride Level:

• Designed for quick, precise leveling of alignment telescopes and collimators to one arcsecond.
• Can also be used to level any cylindrical surface between 1¾” and 3” in diameter.
• Both ends are viewed simultaneously via prisms and a magnification system.
• “Coincidence” or “split” bubble presentation provides the most accurate reading of the bubble position.
• Top-mounted turret assembly rotates 360°, allowing viewing from all sides.
• Elastic strap is included to secure the level to the instrument.
