Mirrors are available in a variety of sizes and shapes. In addition to shape and dimensions, the primary factors that need to be considered when specifying a mirror are: the reflective coating, the substrate material, the flatness or surface accuracy, cosmetic surface quality.
|
|
|
Mirrors are smooth, and contain a highly polished surface for reflecting light. The reflecting surface is usually a thin coating of aluminum or silver. Most mirrors for optical applications are called front surface types since the coating is on the front surface thereby eliminating the optical properties of the glass from affecting the incident or reflected light. The rear surface is usually fine ground. All of the following mirrors have a protected Aluminum coating applied to the front surface.

Dicool - optical mirrors that optimise the quality of light
Dicool optical mirrors maximise the power of lamps and the performance of luminaires.
Cool, efficient light
- Reflection rate: Approx: 91%
- Reduction rate (IR): Approx. 85%
- Reduction rate (UV): Approx. 96%
Easy on the environment
Reduces waste at relamping by approx. 90% because you only have to replace the lamp.
Choice of colour temperature
2000K, 2200K, 2400K, 3000K and 4200K series are available

Ball Lenses
Ball lenses are used for various tasks such as improving the coupling between optical fibers and the emitters or detectors they interface with. Standard size lenses range from 1.0mm to 5.0mm. Custom-made sizes or special materials are also available. All Ball Lenses can be ordered with full-surface anti-reflection (AR) coating..
The effective focal length of a ball lens is given by the following formula:
BFL = F – D/2 and EFL = nD/4(n-1)
The Numerical Aperture, NA, of a ball lens is dependent on the focal length of the ball and on the input diameter, d.
NA = 2d(n-1)/nD
Specifications
Material: BK7 grade A optical glass
Diameter tolerance: ±0.005mm
Sphericity: ±0.003mm
Surface Quality: 40/20
Coating: none
Drum Lenses
A Drum Lens is a variation of a ball lens where a portion of the ball is ground down to a smaller diameter. These lenses are used in similar applications to those of ball lenses. The drum lens adds the ability to handle and package it in a different way.
Specifications
Material: BK7 grade A optical glass
Diameter tolerance: +0.0/-0.05mm
Length: ±0.005mm
Surface Quality: 40/20
Coating: none

The plano convex lenses listed are made with BK7 glass however any glass type may be used. The lenses are designed to work best at infinity or near infinite conjugates.
The lenses have a standard AR coating but any type of multilayer coating may be ordered. Most lenses are in stock and can be shipped within 24 hours. Westech can produce a custom lens from any drawing or specification.
