Used Lightwave 120-02

APT 280AN Gallium Arsenide Wafer Titler. Exposes up to 16 easy to read alphanumeric characters across the wafer flat or at 3 other selectable locations in 90 degree increments from the flat. It handles 3 to 5 in. wafers.

Burleigh HI Fase 800-1 Etalon System. 760-840 nm. Only what is in the photo. No power supply or cables. Cannot test unit but will give the 30 day money back option.

Rofin Ultra Waferlase® Laser Marking System. Cassette to cassette integrated laser marking system for marking silicon wafer from 4 in. dia. to 8 in. dia. This turnkey system allows you to mark wafers with alphanumeric and barcode tracking information. This system is for deep markings on the wafer. Uses a 65W Nd:YAG laser TM00 Mode Class 4. 208-240V, 3 Ph, 50/60 Hz, 30A, CE.

Avtech AVOZ-B3-B-P Laser Diode Driver Pulsed Voltage. The AVOZ-B3-B high voltage high current pulse generator can provide up to 100V/100A into a 1 ohm load (or 1 ohm in series with a laser diode), making it suitable for testing high power laser diodes and laser diode arrays. The pulse width is adjustable from 100 ns to 2 us, with 35 ns rise and fall times. The maximum pulse repetition frequency (PRF) is 10 kHz, and the maximum duty cycle is 1 percent. The maximum average output power is 100 Watts. Laser Diode Driver (Pulsed Voltage) AVOZ-B3-B: Base model. Units with the -B suffix include the IEEE-488.2 GPIB and RS-232 computer control feature (/gpib) and a 2 m/6 ft GPIB cable. Positive Output Polarity: A polarity must be specified. 115-230V, 50/60 Hz.
