Knight Optical’s Plane Mirrors for Fibre Optic Applications

24 Jun 2018

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

Our plane mirrors are used within fibre optic applications such as testing the fibre optic signal to help understand the strength of the signal.

Plane mirrors also known as front surface mirrors or first surface mirrors are used widely within Fibre Optic 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.

Typical specs:

Material: Soda lime float glass, BK7 or equivalent
Diameter Tolerance: +0/-0.2mm

Lengths/ width: ±0.3mm (≤100mm), ±0.5mm (>100mm)

Thickness: ±0.25mm
Surface Quality: Flatness:

1.1mmthk: 1λ over 10mm dia.

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.
