Knight Optical’s Plane Mirrors for Laser Distance Measurements

16 May 2018

Knight Optical can offer you Plane Mirrors (general, λ/1 and λ/4), for use within Laser Distance Measurement Applications in a range of materials such as Soda-lime float glass, white float glass, and BK7 glass.

Plane mirrors also known as front surface mirrors or first surface mirrors are used widely within Laser Distance Measurement applications. As stock we hold a number of general purpose, λ/1 and λ/4 with a range of up to 6 types of coatings such as Enhanced Aluminium, Ali/SiO₂and Ali/Mgf². Our general purpose grade mirrors are made from good quality float glass and generally available in thicknesses of 1mm, 3mm and 6mm as standard.

Laser Distance Measurement devices utilise the use of a laser beam to be able to determine the distance of an object. How optical mirrors are used in conjunction with these devices is that, a mirrored surface can be measured with a laser tracker; which will help determine the distance between the laser distance measurement and the mirror at its current location which would be the target in question for ascertaining its distance.

3/6mmthk: 2λ over 25mm dia.
Parallelism:

All our Flat Mirrors are fully inspected on their quality in our ISO 9001 certified, state-of-the-art Metrology laboratory, our ZYGO interferometer and Radius Slide tests for the form error, irregularity and TWE on flat and spherical surfaces, and Starrett AV300 provides video imaging for non-contact testing on small dimensions. This allows 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 lack of space.
