Glass

Optical Filters carries an extensive range of glass available in sheets or custom machined.

Plain float glass

  • Cost-effective
  • Excellent optical clarity and transmission
  • High scratch and chemical resistance
  • Can be laminated for impact resistance and safety
Windows up to  2000 x 1200mm (78 x 47”)
Standard Thickness (mm) 0.8, 1.1, 1.6, 2.0, 3.0, 4.0 , 6.0mm 
(0.03, 0.04, 0.06, 0.08, 0.12, 0.16, 0.24”)

Finish

We offer high quality finishing services, with a range of edging including clean-cut, flat ground, beveling and polishing.

Anti-Reflective Glass

Anti reflective (MLAR) coatings will reduce the reflectance of plain glass by about 9 times to less than 0.5% across the visible spectrum.

Windows up to  812 x 1270mm (32 x 50”)
Standard Thickness (mm)

1.1, 1.6, 2.3 & 3.0mm 
(0.04, 0.06, 0.09 & 0.12”)
Other thickness supplied by optical lamination

Non-glare Etched Glass

  • Glass with an acid-etched surface finish provides a high performance dispersive non-glare front surface
  • This is a cost-effective solution where signal image quality is not critical. The further the non-glare surface is from the display, the greater the image haze
  • Using a non-glare etch on the front screen of a CRT display can cause an interference with the light etching on the tubes. This will result in a coloured sparkling effect. To overcome this distortion the screen should be positioned at least 10 cm from the display.
Windows up to  1600 x 920mm
Standard Thickness (mm)

1.1, 1.6, 2.0, 3.0, 4.0mm
Other thickness supplied by optical lamination

Chemically Tempered Glass

  • At least two and a half times as strong as traditionally tempered glass· Five times as strong as un-tempered glass
  • It can be ground, drilled and cut without any risk of breakage
  • Chemically tempered glass, when laminated, will have a localized break pattern for better visibility
Minimum thickness 0.5mm
Maximum part size 400 x 500mm
