Contact for price and availability

spectraval 1511focus can be used for the measurement of small light emitting objects as LED chips, the segments of alphanumeric displays, back illuminated signs and mini CCFL tubes. It has a specifically modified measuring optics compared with the standard device spectraval 1511 and can be used in combination with focussing optics accessories to measure diameters of 3 mm, 1 mm and 0.5 mm in defined distances. The 0.5 mm version will be adjusted with a magnifying glass to increase the positioning precision.

All optics can be attached easily to the basic instrument by screwing. The used version of the front-end is automatically detected by the instrument and the appropriate calibration data set will be applied.

The instrument can be used in a stand-alone mode thanks to its touchpad display.

Highlights:

  • Compact solutions
  • Fast measurement
  • Precise results due to high quality spectrograph and NIST traceable calibration
  • Comfortable handling due to Bluetooth connection
