Linear sheet polarizers are used for a broad range of applications including the production of LCD monitors and TVs, photography and other lighting and entertainment systems such as projectors. Our UV and IR sheet polarizers extend the spectral range down to 290m for the HNP’B replacement material and HR is used between 800nm to 2000nm. We have extensive stock of HR material in 76.2mm square sheets. The range from 800-860 the HN7 type offers superior performance at a reduced price. Working below 800nm HN22 is an ideal choice. Knight Optical supply linear sheet type polarizers in a range of types. These sheet polarisers were formerly supplied by Polaroid/3M under the Vikuti brand. Although these sheets have since been made obsolete by the manufacturer, Knight Optical holds substantial stock of the original material including HN32, HN38 and HN42, and performance HN22, HN38S and HN42HE high extinction sheets Read PDF for information

The waveguide dehydrator is a crucial element of any communications waveguide system, be it a microwave, radar, TV satellite terrestrial or antenna system. This high-capacity waveguide dehydrator for location in both ETSI and standard 19” racks, has reversible mounting brackets allowing the same unit to fit within either enclosure without any further need for mounting brackets or plates. Whether you choose the 230vAC or the 48vDC variant, the 12446 boasts an impressive output of over 220 litres per hour at an excellent dewpoint of -40ºC. The unit comes with 2 fixed output pressure options of either 15 or 40 mbar, and 6 off ¼” pneumatic outlets as standard. Despite its physical dimensions, the 12446 houses a high capacity, high pressure air storage vessel which allows the unit to remain inactive for extended periods of time, keeping maintenance requirements to an absolute minimum. Dry air delivery: 8 ft3/hr Dry air dew point -40c Output pressure 0.2 – 6 psi

Yapalong Radio Technology Yapalong is the name of our brand of full-duplex radio communications system, allowing for two-way conversation between users simultaneously. This results in a natural, phone-like conversation, and is compatible with open microphone and push-to-talk function. As this is our own IP technology, we have been able to develop a competitive product offering good range, sound quality, and group size, while also being good for your budget. One major point of difference between Yapalong and its competitors is our unique "no-master" feature. Some companies advertise no base station, but there is always a master unit involved that handles this functionality, which ruins your connection should anything happen to the master. Not with Yapalong - our mesh network does not need a base station or master unit, which makes operation flexible and the connection robust. As long as at least 2 units of the same group are within range, they will be able to communicate.
