Dichroic-lenses-2 What Is A Dichroic Filter?

A dichroic filter, thin-film filter, or interference filter is a very accurate color filter used to selectively pass light of a small range of colors while reflecting other colors. By comparison, dichroic mirrors and dichroic reflectors tend to be characterized by the color(s) of light that they reflect, rather than the color(s) they pass.

os050420-01lo Compact Measurement System For LED Luminaires: Ophir® FluxGage™ 604 Series

The Ophir® FluxGage™ 604 series is a compact measurement system featuring four additional color sensors that are evenly arranged in the bottom of the device delivering further x, y, and CCT data besides the illuminance. The system provides an overview of the color and overall uniformity of the measured light in seconds, allowing for the direct evaluation of LED chips or optical assemblies used for color mixing and beam shaping.

  • Standard Photodiode Power Sensor: PD300

    The Ophir PD300 general purpose photodiode laser measurement sensor features a swivel mount, a removable filter, and a 10 x 10 mm aperture.  Without a filter, its spectral range is 350 – 1100 nm and its power measuring range is 500 pW – 30 mW. With a filter the spectral range is 430 nm – 1100 nm and the power range is 200 µW – 300 mW.

  • High-Speed Optical Power Meter For Fast Photonics Alignment Applications: F-712.PM1

    PI introduces the new F-712.PM1 high-speed optical power meter for converting the optical signals and currents of photodiodes into a high-resolution, logarithmic analog voltage signal. The meter also boasts a bandwidth of 20 kHz and extended wavelength range of 400 to 1550 nm.

  • High-Performance MWIR InSb Camera: FLIR X6800sc

    The FLIR X6800sc is a fast, highly sensitive MWIR camera designed for scientists, researchers, and engineers. With advanced triggering and on-camera RAM/SSD recording, this camera offers the functionality to stop motion on high-speed events both in the lab and at the test range. The X6800sc has a cooled FLIR indium antimonide (InSb) detector and captures full 640 x 512 images at 502 frames per second, or up to 29,134 Hz with windowing.

  • Five Axis Piezo Nanopositioning System: Nano-Man5

    The Nano-Man5 is a 5-axis piezo nanopositioning system with closed loop feedback control for absolute position measurement. The compact design makes it easy to integrate into existing instrumentation. The Nano-Man5 is designed for alignment applications that require 3 linear axes combined with tip/tilt capabilities. The included position sensors ensure picometer and nanoradian accuracy under closed loop control.
