New Development with Interesting Advantages - Pyroelectric LTO Detectors in Current Mode

The LASER COMPONENTS Pyro Group introduces new developments: Pyrodetectors used in current mode.

In current mode, the signal is relatively strong on a low offset with a consistent temperature dependency across a wide range. Alan Doctor, pyrodetector visionary and managing director at LC Pyro Group has had current mode in his sights for years and transformed it into marketable products. In addition, the new product range reflects new market trends.

The initial products consist of LiTaO3 detectors in a TO-39 housing - as single and dual sensors with an active area of up to 3.0 x 3.0 mm². They are available both with and without an additional blind element. The purpose of the blind element is temperature fluctuation compensation (TFC), as well as higher internal amplification. Wherever reasonably possible, we integrated microphonic reduction in the detectors.

A wide range of filters makes it possible to configure a suitable detector for nearly any application.

US Digital - E4T Miniature Optical Kit Encoder

US Digital is pleased to announce the launch of the E4T, their latest series of miniature high performance optical encoders. The E4T series delivers a marked performance increase over similar encoder models and designed to be an enhanced replacement for the E4P encoder series. The E4T utilizes state of the art transmissive optical sensing technology, and incorporates US Digital's own proprietary OptoASIC. Assembly of the E4T is simple and efficient and retains the previous E4P's form factor. Key features of the new E4T include: • Mechanically and Electrically Interchangeable with E4P • Improved Quadrature Signal Strength • 100 kHz Frequency Response • Transmissive Optical Design • Collet Style Push on Optical Disk Design (Patent Pending) • Simple & Efficient Assembly Process As with all of our products the E4T is designed and manufactured in their Vancouver, Washington USA facility and is available for purchase as of December 2014.
