Optical Components : We hold with Solaris Optics the complete technology for the production of optical components. Nearly all types of optical glasses, quartz glasses and crystals are used for our products. Our possibilities include the coating procedure by thin-layer technology, high precision mounting of assemblies and the MRF corrective polishing. The portfolio contains plane optics (e.g. prisms, wedges, plane plates, mirrors and polarizers) and spherical optics (e.g. lenses, achromates, triplets, objectives, concave or convex mirrors).

Infrared-Detectors : The heart of the VIGO-products are IR-detectors and complete modules for the spectral range 2 – 16 µm with highest sensitivity and very short response times. Photo resistors, Photo diodes and PEM-detectors are available, completed by preamplifiers and cooler controllers. Suitable mechanic mounting aids and heat sinks are available as well . The infrared detectors are based on II-VI semiconductors (HgCdTe) and also on materials from the III-V element groups (InAs and InAsSb).

Laser modulators : Our Pockels cell are based on the electro-optical crystals LiNbO3 and KD*P. The principle operation of the  electro-optical modulators based on the voltage induced birefrigance. Polarizers and High-voltage drivers complete the delivery program.

 Service laser marking and engraving : At our facility in Strausberg DoroTEK has established  laser job shop. We have modern laser marking systems on base of Fiber laser, Nd:YAG- and CO2-laser. Our laser engravings are a precise and esthetic way of marking for industry and advertising.
