Description

PRODUCT DESCRIPTION

CALIBRATION PLATE   
This precision glass emulsion calibration plate is designed for use in all of the A3 scanner based ScanCAD products. It replaces the factory supplied grid in case of damage, as well as providing a backup plate in case of breakages.

 

BASE MATERIAL  
Soda Lime glass with a photographic emulsion silver halide image exposed onto the surface. The finished product has a "black" effect on clear glass. The plate is available in both 5mm and lower cost 3mm versions. The plate is coated with a special emulsion protection to make the surface more durable.

 


PRODUCTION TURNROUND  
Our standard turnround is 7 days for this product. We can offer faster services if required for more urgent orders.



INSPECTION

Full Certificate :   The grid is supplied with a measured calibration certificate that is traceable back to NIST standards. Each plate is individually marked with a serial number.

Specifications

SPECIFICATION

Emulsion Glass used for photo-masks have the following component layers:  a soda lime glass base and a photosensitive emulsion layer (silver halide).

When we expose the plate in the imager, the light energy from the laser interacts with the silver halide crystals suspended in the coated gelatine layers. Development, a chemical process, converts exposed silver halide grains into metallic silver. The next step in the chemical process is fixation. The fixer stops development and removes the unexposed silver halide grains in non-image areas. Finally, the plate is washed/dried/cleaned and inspected.

The final result is a ‘black’ image coated on one side of the plate. The density of the emulsion is very high, typically Dlog of 4.5 – 5, giving it an excellent opacity to all common light sources.

One concern with emulsion glass is robustness. The Gelatine/Emulsion is relatively soft and must be handled carefully to avoid damage and scratches.

Our photo-masks are produced in conditions of 21deg C , and if dimensional accuracy is a concern when using the mask, then you must replicate these conditions in your own clean rooms and acclimatise the mask in these conditions for upto 4 hours before you intend to use it – only then can it be considered to be dimensionally accurate and stable.
