REFLECTIVE COLLIMATORS
Description
Providing convenience and portability, Optical Surfaces offers a comprehensive range of fully enclosed pre-aligned reflective collimators. High stability and performance is achieved by a zero expansion off-axis parabola, manufactured to exacting standards. The optics within the instrument, are secured by the use of stress-free mounts and aligned in our laboratories for optimum performance. One major advantage of these collimators is that due to their achromatic design, they will perform at any wavelength from UV to IR.

Frequently Asked Questions
Reflective collimators can be used to calibrate other optical devices, to check if all elements are aligned on the optical axis, to set elements at proper focus, or to align two or more devices. They are the optical system of choice for applications including MTF testing.
Optical Surfaces' reflective collimators have standard apertures up to 300mm, wavefront accuracy > λ/5 p-v at 633nm, tube or cube section, a range of coatings, a variety of output ports and platforms, temperature stabilization using Invar tie bars (option), vacuum compatibility (option), and cleanroom assembly (option).
A reflective collimator is an optical assembly that takes divergent or convergent incoming light rays and produces parallel light output.
One major advantage of these collimators is that due to their achromatic design, they will perform at any wavelength from UV to IR.
As the demand for higher quality, higher resolution optical systems for integration into sophisticated imaging systems has become more prevalent, many designers and scientists have chosen MTF measurement as a flexible and accurate system characterization tool.
