Optical Coatings

UQG optical coating service provides a broad range of coating options that are applied to our range of optical components and glasses. The range of coatings available includes the UV to IR region.

Anti reflection coatings are used to improve the transmission of the transmitted light and improve the contrast of the image. An uncoated glass surface has surface reflection of approximately 4% per surface, AR coating will reduce this to as low as 0.20%.

Options (400-700nm) Single layer MgF2 R= < 1.5% per side Multi layer R= < 0.5% V Coat R= < 0.25% @ specified wavelength Dual wavelength (eg. 532nm + 633nm) AR coatings for the UV (eg. 254nm) and IR (eg. 1064nm). Please contact us for further information.

Aluminium and metal coatings for reflection of images and light.

Options: Aluminium – protected SiO R= 85% - 94% @ 550nm Aluminium UV protected MgF² for use in the UV Gold protected for the IR

Metallic nd filters – Reflective neutral density filters for the UV to IR stock
Beamsplitters – Cube, polka-dot, plate, 50/50 Fused Silica and colour
Hot Mirrors – Shortpass Filter reflecting the IR and transmitting the visible 
Cold Mirrors – Reflecting the visible light while passing the IR 
Dichroic Colour Filters – Addition and subtractive 
ITO – Electronically conductive for electrical conductivity and anti-static 
UV Blocking – Blocking ultraviolet radiation transmitting the visible region 
IR Cut off – Blocking infrared transmission while passing the visible region 
Colour Separating - Beamsplitter Mirrors sharp separation of transmitted and reflective regions 
Colour Correction – For tungsten and daylight conversion to change colour temperature
