Beam Collimators for MTF Optical Testing

Beam Collimators for MTF Optical Testing

Optical Surfaces Ltd is a leading supplier of Beam Collimators tailored to enable precise Modulation Transfer Function (MTF) testing of your optical systems. MTF is a trusted technique for objectively evaluating the image-forming capability of optical systems. Reflective beam collimators are mirror assemblies that take divergent or convergent incoming light rays and produce parallel light output. They can be used to replicate a target at infinity without parallax. As a consequence, ...

Illustrated Guide to Aligning Off-Axis Paraboloids

Illustrated Guide to Aligning Off-Axis Paraboloids

Optical Surfaces Ltd. announces that it produced an updated version of its popular 'Practical Guide to Off-Axis Paraboloid Alignment Procedures'. Off-axis paraboloids, also referred to as off-axis parabolic mirrors, provide the advantage of an unhindered aperture and access to the focal plane. They are ideal for broadband or multiple wavelength applications, thanks to their complete achromatic performance. Off-axis paraboloids often deliver the most cost-effective solution without compromising performance to many problems ...
