Miniature Linear Encoder

NUMERIK JENA unveiled its LIK 2 optical linear encoder series designed for applications where motion feedback is required inside the vacuum chamber. The non-contact encoder has been designed for environments with 10-9 mBar of pressure and has an non-magnetic option. The series has a 20-micron grating period and the graduation is applied to either a glass or steel scale substrate. The LIK 2 encoder system can be baked out for 12 hours at 130 degrees C. The scanning units can provide a 1 Volt peak to peak or TTL output with resolutions down to 50 nanometers.
