Laser Hologram Linear Encoders
Sony Laserscale is an ultra-high accuracy linear scale using hologram grating and semi conductor laser read head.
The BL55 high accuracy scales require no separate interface, resolution to 0.01µm.
BL55-RU (Enclosed scale with zero point)
BL55-RE (Open scale with zero point)
BL55-NE (Compact open scale)
BS76/78 ultra-high accuracy system requires BD interface detector, resolution to 0.14 nanometer can be achieved.
BS76-NS/N (for use in vacuum)
BS78 (latest compact model)
BD15 (Detector series VME card)
BD60 (Detector, 0.1µm resolution)
BD95 (Detector series to 0.14nm)
