UQG Optics Ltd > Services > Optical Coatings, Windows, Flats

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

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.

Front Surface Mirrors

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

Additional custom optical coatings supplied include:

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
