November 2012

New option with microimmersion lenses  for the broad band photodiodes appeared with peak wavelengths at 3.3, 4.2 and 5.2 μm (the PD33fs miL, PD42fs miL and PD52fs miL respectively).

November 2012

Sr/Su PDs for the 4.2 μm wavelength will have two modifications: with broad and narrow spectral bandwidth.

November 2012  

Amplifier and PD have been integrated into a single case so that it is possible to get now a PD module. Specifications are to appear soon.

November 2012

Implementation of new type of LED chips lead to higher output power in the IRS LED series emitting at 870 nm.

October 2012


The OPLED70 will have the Sr/Su header instead of  the previous TO-39 type of package.

August 2012

Production of  TEC based devices with 16 pins  has been currently terminated and thus these types of devices can be supplied on a limited number basis only. Our current stock contains several 16 pins devices. Please, consult on a particular device type before making an order. We recommend using 12-pins devices.
