Integrating Sphere ISP PTFE Precise measurement of UV-/IR-LEDs

The portfolio from Instrument Systems comprises complete measurements systems for the whole spectral range. A wide selection of integrating spheres made of PTFE material in combination with high-quality spectroradiometers of the CAS series enable ultrasensitive measurements of radiant power especially in the UV and IR wavelength range.

The Integration Spheres ISP PTFE with 75, 100, 150 and 250 mm diameter offer three configurable measuring ports. Thus, several measuring devices, i.e. photodiode or spectrometer, can be connected. The middle port can be equipped with a connection for an auxiliary light source for self absorption correction. The highly reflective PTFE coating ensures high throughput, also in the critical ranges UV and IR.

All measuring systems with PTFE integrating spheres are delivered with calibration traceable to PTB.

Typical production applications are for small integration spheres ISP PTFE e.g. wafer probing and chip testing, for larger ISP PTFE e.g. single-/multi-chip testing.

PTFE spheres are used in the lab both in actual product development of IR VCSEL and EEL lasers, IR and UV-LEDs and for building reference systems for the production of UV and IR light sources.

To ensure optimal performance, we recommend applying a specialized pretreatment to the integrating sphere when used with UV radiation. This enhances stability in the UV range from 200 nm and reduces fluorescence effects. Please contact us for more information.
