Knight Optical’s Colour Glass Filters for Laser Range Finders

31 May 2018

Laser Range Finders is a range finder that utilises the use of a laser beam to be able to determine the distance of an object. Laser Range Finders are most typically operated on the principle of sending a laser pulse in the form of a narrow beam towards the object of interest and then measuring the time taken for the laser pulse to be reflected from the target in question and received by the sender.

Knight Optical offers Colour Glass Filters for such an application, be it either short pass, long pass or bandpass filters. We can also offer these as customised filters with specific band blocking coatings to optimise your wavelength of choice.

We hold a massive inventory of Bandpass, Long pass, and Short pass.

All our Colour Glass Filters are checked for quality in our state-of-the-art Metrology laboratory using our Varian Cary 5000 spectrophotomer’s fitted with UMA, allowing us to work to the highest QA standards and meet the tolerance specifications on these precision components.

Knight Optical offers comprehensive testing of optical components in our state-of-the-art metrology facility. This is not just exclusively used for optical components manufactured by Knight Optical, it is also a sought-after testing facility for customers who do not have the equipment themselves, due to the expense of the equipment and it taking up a lot of space.
