Optical Surfaces Beam Collimators are manufactured to better than lambda/10 p-v surface accuracy. OSL produces no central obscuration and obtains efficient transmission.
Beam collimators are optical lens assemblies that take divergent or convergent incoming light rays and produce parallel light output.
They can replicate a target at infinity without parallax.
Beam Collimators can 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.
OSL Beam Collimators are suitable for MTF testing, optical resolution testing, star simulation, MRTD testing and boresight alignment and inspection.
OSL Beam Collimators have an achromatic all-reflecting design.
By adding aluminium / magnesium fluoride coatings, the Beam Collimators can operate from UV to infrared without adjustment.
Using zero expansion glass mirror substrates, OSL Beam Collimators provide exceptional operational stability.
Each system has an output port datum plane giving a defined distance to the focus.
All Beam Collimators provide a 20mm field, ensuring full compatibility with standard black bodies.
All optics within OSL Beam Collimators come pre-aligned in stress-free mounts.
Each of the Beam Collimator's three feet are adjustable by +/- 10mm for centre height positioning.
The OSL range can be transported between sites while maintaining alignment.
For applications demanding the highest reflectivity and high damage threshold, ultra-hard dielectric, protected silver and gold laser coatings are available.
Athermalised Beam Collimators are available for applications requiring operation over a wide temperature range.
Standard models include exit apertures of 100, 120, 150, 200, 240 and 300mm.
Customised systems can be supplied with larger field sizes, different output interfaces and platforms.
Other options include reticle holders, lamphouses and black bodies.
Test interferogram and analysis showing wavefront accuracy, focal length and working distance are supplied with every Optical Surfaces Beam Collimator.
