Measurement Aperture Mask, 20 x 15 mm (Legacy, Generation II)

Product Code E361
Price $90.00 ex. VAT

Measurement aperture masks with electrochemically-etched holes to accurately define the active area of a pixel during measurement and to stop indirect/scattered light.

Useful for OPV measurements under solar simulators or OLEDs with luminance meters. For use with pixelated cathode substrates (S171) in the push fit test board.

  • E361 is designed for use with the single large area pixel.
  • E362 is designed for use with six small pixels for most general measurements where the scattered light between pixels (typically less than 1%) is not an issue.
  • E363 provides a set of three masks such that individual pixels can be masked.

There is a newer version of this product. Our generation I and II substrates and masks will be discontinued soon and are only available while stocks last. Please contact us for further details.
