What's new

The Model 715 I is designed to work with unpolarized or ramdomly polarized lasers. The product replaces the conventional glan polarizers with calcite displacers at the input and output of the Faraday Rotator Asembly. Calcite crystals, when properly orientated, will generate two parallel beams with orthogonal polarizations.

The input calcite displacer splits the incident beam into two liear polarized beams. The separation of the two beams is determined by the length or the calcite displacer, and is designed to pass through the Faraday Rod.

The output calite displacer recombines the two beams into one randomly polarized beam.

The Model 715 I Specifications:

Aperture:	1.7 mm
Transmission:	> 92%
Tuning Range:	965 TO 1135*
Offset:	2 mm

* Also avalable as a non-tunable @ 1064 nm

Model 275 Amplifier Modulation systems dc to 8 MHz ( -3db)

(Danbury, CT - May 1, 2004) Conoptics, Inc. has introduced the Model 275 linear, high voltage differential amplifier designed to be used with various Conoptics electrooptic modulators. The output of the amplifier is designed to drive the modulator configured as a lumped capacitor. The amplifier is capable of delivering in excess of 275 volts peak to peak into a capacitive load from DC through 8 to 10 MHz depending on modulator total capacitance. The system may also be used as a high frequency electrooptic beam deflector driver, for mastering a variety of different format DVD and CD rom applications. A DC bias control is also provided to allow positioning of the quiescent operating point of the modulator or as a DC centering adjustment for beam deflector applications. The amplifier requires only 1 volt into 50 Ohms to deliver it's maximum peak to peak output signal to the load.

LASSII-RM

Conoptics LASSII-RM is a rack mountable version of the standard LASSII. The system is designed to be used in large optical mastering systems and other rack mount applications. The unit has a remote connector which allows the user to control all of the front panel functions from a remote location or from a computer with an I/O board. All specifications are similar to the standard LASSII, except that the feedback bandwidth is somewhat reduced due to the 3M cables between the E.O. modulator and the rack. The rack is 2U high (3.5”) by 12” deep.
