Custom Optical Windows
Sydor Optics Inc.Request Info
Sydor Optics has extensive experience in double-sided grinding and polishing of custom optical windows. IR to UV applications in the industrial, medical, research and defense industries typically include Debris Shields, Laser Windows and Heads Up Displays (HUDs).
From prototype to high volume production quantities, our precision manufacturing capabilities include:
•
Diameter: ≤600mm diagonally
•
Thickness: ≥0.1mm
•
Thickness Tolerance: +/-0.003mm
•
Surface Flatness: ≥ 1/20 wave
•
Surface Quality (scratch/dig): 10-5
•
Surface Roughness: 3-15 ?
•
Parallelism: <1 arc second
•
Transmitted Wavefront Error (TWE): ≥ 1/20 wave
•
(all tolerances are part size, material type and thickness dependent)
Common glass substrates include Borofloat, BK7, Fused Silica, Synthetic Quartz, CaF2, MgF2 and more.
We are excited to announce our new double-sided grinding & polishing capabilities with the addition of the PR Hoffman Servo RS 6600 machine. The 6600 was custom engineered by PR Hoffman based on our need for a smaller thickness on large format optics. The older Mark IV double-sided machines were capable of polishing parts up to 24” in diameter down to a 3mm thickness. The new 6600 can polish the same 24" part but now achieve a thickness down to 0.8mm with the goal of hitting 0.5mm with further process development.
In addition to achieving a smaller thickness the 6600 will allow for more control over surface flatness, surface quality and TTV. These capabilities mean that Sydor now has the ability to manufacture larger windows (debris shields, HUDs etc.) with a reduced lead time.
PR Hoffman will be offering the new 6600 machine as part of their standard product line. We recently placed an order for a 3rd 6600 and will be the first to receive one fresh off of the production line. The 3rd machine should be operational by May 2015.
Sydor Optics is ITAR registered & ISO 9001:2008 certified.
