We manufacture photomasks and custom patterned optics for commerical, military and university applications.
Our Frequently Asked Questions (FAQ) page is updated regularly based on customer feedback. Please check back often.
Yes, we have the capability to work with 200 millimeter wafers.
Yes. Our glass shaping team can core drill inner and outer diameters. We can also create inside cuts, angles and radiuses. For simple square or rectangle products we use our dicing saw technology.
Currently, we do not have the equipment and tooling to work with .1 millimeter glass.
We also accept raster and vector files. In addition, we can work from drawings, sketches and simple descriptions. Currently, we are working on the upload site to allow a larger variety of formats.
At this time, we do not have a process for sputtered ITO. This is due to lack of demand.
A 4 to 6-inch chrome mask will ship 48 hours after plots are approved and payment is received. 8-inch and iron oxide will ship in 72 hours.
The factors that determine the “edge quality” or smoothness is the C.D. and tolerance and tool.
Shipping is an additional cost which is determined by the customer.
PCM means process control monitor. This is a test pattern that we place along the edge of every mask. It contains several designs that allow us to quickly verify that the equipment and process remains within the required parameters.
- Sodalime: Basically it’s window pane glass and cheap.
- Borosilicate: Optical Glass – This is a common type of material for optical components.
- Quartz: Generally used for UV photomask applications.
Klayout – klayout.de (It’s free) A good layout tool but not a great editor but lots of strong features under the hood.
On the higher end… DW2000 from Designworkshop (Canada).
Which substrates can Indium Tin Oxide (ITO) be patterned on?
- We can apply ITO to most hard surface subsrates (Glass, Si, Alumnia, etc…).
What is the range of thickness for these substrates considered max/min?
- The common substrate thicknesses are 0.300mm – 0.250” .
Does Photo Sciences do small-scale orders?
- Yes we do small scale orders.
It’s cheap and readily available and works great in the VIS range.
