SpotOn Analog
Main Applications:
Measures laser displacement in real time, at a rate of up to 30 KHz bandwidth.
Measurement of fast steering mirrors
Monitors vibration and deflection at high bandwidth from long stand-offs
Perfect for closed loop applications
For fast and extremely accurate laser position sensing
Versatile: Measures both Position and power using two-dimensional position sensitive detectors: compatible with our Lateral Effect PSD’s 4mmX4mm or 9mmX9mm
Easy to use: Just connect the output to a scope or DVM to observe movement in µm units (1Volt=1000µm)
Precise: Large area detection with sub-micron resolution and linearity better than 0.5%
Compact:Slim design sensor heads and elecronics box.
