NOUN
- a small telescope attached to a large telescope to use in setting the line of the larger one
- optical device consisting of a tube containing a convex achromatic lens at one end and a slit at the other with the slit at the focus of the lens; light rays leave the slit as a parallel beam
How To Use collimator In A Sentence

- The optical head has two collimators, each 33 cm long: the sun collimator (without lens) and the sky collimator (with lenses).
- Based on the alignment measurements such as level meter, gradienter and laser collimator, the instructional software for straightness measuring and evaluating is developed.
- I do not carry ammo in mine - that's a big NO-NO in California South - but I carry several calibres in "bore snakes" and a collimator, plus a copy of local legislation, to balance that. My Range Bag
