New England Photoconductor’s range of thermoelectrically (TE) cooled indium gallium arsenide (InGaAs) photodiode series comprises IC1 (1-stage TE cooled, -10°C) or IC2 (2-stage TE cooled, -20°C) versions, suitable for typical wavelengths of 1300 nm or 1550 mm, as well as extended InGaAs PIN photodiodes that can be used for wavelengths up to 2600 nm: IE6C1 C1 (1-stage TE cooled, -10°C) or IE6C2 (2-stage TE cooled, -20°C).

Wavelength Range 1.2-2.6 µm; Active Area Diameter 0.5-5 mm; Responsivity 0.80-1.3 A/W; Dark Current 0.03-50 nA; Capacitance 60-3500 pF

Each individual part and each optical assembly is manufactured by us in specially coordinated processes. Depending on the task, we put together the necessary work steps in a modular manner and gear the production process entirely to the desired result.

Available with active sensor area diameters of 0.5 mm, 1.0 mm and 2.0 mm, the AP300-T2 is an amplified extended InGaAs sensor with a 2-stage thermo-electric cooler (TEC). A low-noise amplifier provides detector-noise limited performance up to 2.6 µm in a compact package. You need an OEM custom configuration?

We also adjust the properties of the cement individually for each component. For this purpose, we combine flat optical and spherical as well as aspherical components with specific cements to form subgroups with multiple optical functions. In this way, we achieve an optimal beam path with maximum performance for each assembly.

Even with multiple media transitions in optical assemblies, we find the right solution that ensures the best beam passage. In this way, we reduce stray light and achieve the highest transmission for components such as deflection prisms, beam traps, projection solutions, beam splitters and much more through our machining.
