| Notes: |
(a) The power is calculated by measuring the pulse energy and exposure time. A rectangular pulse is assumed for this calculation.
(b) May be used at 550 - 900nm with decreased accuracy and higher reflection (up to 10%).
(c) Use without window or diffuser. The sensor does not measure pulse width above 1100nm. For pulsed power measurement at >1100nm, a short pulse with known duration should be applied. A pulse
energy measurement is performed and divided by the known pulse width to obtain the power. When working without window and without diffuser, the sensor is not sealed against dust or water.
(d) With diffuser, reading will be up to 10% lower than vertical beam and beam should be offset from center in opposite direction to beam incidence by ~10mm.
(e) At room temperature.
(f) Faster cooling can be achieved by attaching the Ariel to a heat sink using the mounting threads at the bottom. |
