About Thorlabs
“Over our history, Thorlabs has invested heavily in the infrastructure and capital equipment needed to manufacture the majority of products we sell. These in-house manufacturing capabilities also give us the freedom to develop OEM solutions. Consequently, we are able to partner with you, not only during the concept phase when one traditionally buys a basket of items in small quantities, but also when you reach full production and need a partner capable of manufacturing quantities of select items to exact specifications that can be called off as needed.”

About greenTEG’s gRAY sensors
These Thermal Optical Power Detectors include unmounted and mounted single-thermopile sensors, as well as mounted position detectors comprising four individual thermopile sensors that are mechanically integrated into a quadrant configuration. The advantage of these thermal detectors over photodiodes is that the thermal detectors have a spectrally flat response over a broad wavelength range that extends from the UV through the MIR. Additionally, the thermal detectors have negligible dependency on the angle of incidence.
