Both families of devices are especially designed for low-noise detection in the UV region of the electromagnetic spectrum. OSI Optoelectronics’ UV-XXXDQ(C)/EQ(C) series of planar diffused structure UV-enhanced photodiodes show significant advantages over inversion layer devices, such as lower capacitance and faster response time. These devices exhibit linearity of photocurrent up to higher light input power compared to inversion layer devices. They offer better stability with prolonged exposure to UV light. There are two types of planar diffused UV enhanced photodiodes available: UV-XXXDQ(C) and UV-XXXEQ(C). Both series have almost similar electro-optical characteristics, except in the UV-XXXEQ(C) series, where the near IR responses of the devices are suppressed. This is especially desirable if blocking the near IR region of the spectrum is necessary. UV-XXXDQ(C) devices peak at 970 nm and UV-XXXEQ(C) devices peak at 720 nm. Both series may be biased for lower capacitance, faster response and wider dynamic range. Or they may be operated in the photovoltaic (unbiased) mode for applications requiring low drift with temperature variations. The UV-XXXEQ(C) devices have a higher shunt resistance than their counterparts of UV-XXXDQ(C) devices but have a higher capacitance. These detectors are ideal for coupling to an OP-AMP in the current mode configuration.

Cooling Capacity 1-15 kW @+20 °C; Process Fluid Flow Rate 3-30 lpm @≤8.5 bar; 3/8”, 1/2”, 3/4”, 1” Fittings; Temperature Stability ±0.1-±0.5 K Termotek’s P800 series of stand-alone cooling units for optimum ratio of dimensions and performance are used wherever there is a need for precise cooling and the need to avoid integrating the refrigeration unit in a separate machine housing. High performance in a space-saving, mobile housing – this has proved to be a tried-and-trusted combination over many years in all fields of laser cooling, including optical assemblies, in laboratories, in the printing industry and on machine tools and for HSC milling. The practical arrangement of all the components in the compact housing means not only low maintenance requirements but low vibrations and noise emissions too. The P800 recirculating chillers are available for power ranges from 1 to 15 kW. P800 chillers provide active cooling and therefore contain a refrigeration circuit with a compressor and a heat exchanger for a variety of media. Both the refrigeration circuit and the cold water temperature are monitored and controlled by a central control system. The cold water is reliably fed to where it is required by a pump. An optional particle filter in the cold water outlet keeps the circuit clean, and a flow sensor for the return flow guarantees the required stable operation. The waste heat is either emitted to the environment via speed-controlled fans or transferred to a central water circuit via heat exchangers, so that the waste heat can be used, for example, for preheating the process water.
