Resolution 6.1pm Max. response speed 5m/s Laserscale for motion control to achieve both high resolution and high speed High resolution & speed BL50H uses 1.6µm grating pitch. Grating interferometer type scanning head outputs fine signal pitch of 400nm. Dedicated interpolator divides this signal up to 6.1pm resolution. Also, maximum response speed is 5m/s. Wide tolerance for angle BL50H series Low noise BL50H series provide S/N ratio of 13pm under condition of LPF6kHz. Optimized detection optics in BL50H enable wide angular tolerance of ±30min by constant output characteristics to all rotational directions. Excellent interpolation accuracy BL50H realizes excellent interpolation accuracy with combination to BD700 interpolator. ± 50pm/400nm Long-life laser diode Long-life laser diode (the life is longer by 5 times of the conventional product) is used on BL50H, one piece of the laser diode is equipped in one scanning head unit. There is also special type available which is operative in temperature 40 deg. C or more. For detail, please contact our sales office.
