Diffuse Reflection Material now in gray grades

White diffuse reflecting synthetic material with 98% reflection is used in many optical applications including integrating sphere coating, laser cavities or reflectance standards. Gray scale material at different reflectance levels is required in many calibration tasks like qualifying the linearity of optical sensors.
Gigahertz-Optik now offers its new ODMP material in different grades of gray.
Based on pure PTFE ODM98 the material is doped with different density black pigments. Raw material in plate and in block form as well as machined reflectance plates and reflectance standards with protective housings are available. Gray scale ODM with reflectance values of 2%, 20%, 50% and 70% are stocked. Other reflectance values are available on request.

LED Binning with Gigahertz-Optik’s LED Tester

Slight differences in LED characteristics can occur as a result of mass production. To catalog the parts LEDs are commonly sorted into bin classes based on their luminous flux and color properties. The LED manufacturer may do the binning or the party implementing the LEDs may self-bin them. The LED is normally operated and measured in single pulse mode with a few millisecond long pulse width at a specified operating current.
Gigahertz-Optik GmbH has developed the BTS256-LED tester and LPS-20-1500 LED power supply a cost effective measurement system for single pulse binning.

Illuminating Engineering Society of North America

Award for BTS256-LED tester in IES Progress Report / Toronto, Canada

The Illuminating Engineering Society of North America is the recognized technical authority on illumination. Each year the IES Progress Committee offers manufacturers the opportunity to submit significant product developments and improvements to the lighting industry through the IES Progress Report.
Our BTS256-LED tester was one of the products accepted in the 2010 IES Progress Report has been presented at the IES Annual Conference in Toronto on November 8 at the Fairmont Royal York Hotel in conjunction with the annual conference program events.
