DID YOU KNOW?

LTCL4K series is now also available with new LTSCHP1W-GZ green light source, suitable for any kind of sample and specifically tailored for measuring reflective objects and objects with sharp edges.

KEY FEATURES

  1. Reduction of edge diffraction effects.
  2. Enhanced illumination uniformity, especially on large FOVs.
  3. Less sensitive to alignment.

Ordering information

To order the version with the new green LED module use partnumber LTCL4Kxxx-GZ (i.e. LTCL4K060-GZ).

Notes

  1. Beam shape is not circular. See Tech Info for minimun beam dimensions.
  2. Opto Engineering® recommends green light for high precision measurement applications.
  3. Tolerance ± 10%.
  4. At max forward current. Tolerance is ± 0.06V on forward voltage measurements.
  5. In continuous mode (not pulsed).
  6. At pulse width <= 10 ms and duty cycle <= 10%. Built-in electronics board must be bypassed (see tech info).
  7. Nominal value, with no spacers in place.
