Glass Polishing & Lapping

Hefei Ezenda can accommodate a range of specialist precision glass polishing and lapping requirements, large or small. We offer the latest technologies in double-sided planetary polishing. If a laser-quality finish is required, our single-sided machines can polish up to lambda 10 flatness. We can also polish the edges of windows and squares. Windows, plates and substrates are routinely processed in batch runs at competitive rates. A large proportion of our contract polishing and lapping work is carried out to customer-supplied materials.

Materials & Components: Materials suitable for polishing include optical glass, fused quartz, fused silica, borosilicate, float glass, filter glass, silicon, germanium and more.

Double-sided planetary polishing

Dimensions 3mm dia to 300mm dia

Thickness 0.5mm to 25mm (tolerance to ± 0.01)

Flatness To 1 lambda

Parallelism To <10 arc seconds

Surface quality 10/5, 20/10, 40/20, 60/40

For sizes over 300mm dia we use our range of single-sided machines, polishing up to 500mm dia.

Optical Coatings

Hefei Ezenda 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%.

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).
