Optical calcite crystal (iceland spar) both in raw material and semi-finished form or finished form (such as polarizers, waveplates, etc.) ready to be used as per customer's dimension or detail technical specified.
Typical products are rhombohedral shapes, rectangles and rounds, shaped plates, wedges, and cubes
It is carefully selected to eliminate small inclusions, cleavage planes, cloud and mist, point defects and bubbles inside the crystal.
It is known for its properties of transparency and double refraction, used chiefly in the manufacture of polarizing prisms, which are essential parts of polarization components and other special optical instruments.
There are two kinds of E-O modulations. One is longitudinal E-O modulation if the directions of electric field and light propagation are the same. The KDP isomorphic crystals are normally used in this scheme. If the directions of electric field and light propagation are perpendicular, it is called transverse E-O modulation. The LiNbO3, MgO:LiNbO3, BBO and KTP crystals are usually employed in this scheme.

A Pockels cell alters the polarization state of light passing through it when an applied voltage induces birefringence changes in an electro-optic crystal such as DKDP (KD*P) and BBO. When used in conjunction with polarizers, these cells can function as optical switches, or laser Q-switches. Frequently, Q-switches are employed in laser cavities for the purpose of shortening the output pulse, resulting in a light beam with enhanced peak intensity. In order to provide the device best suited to your purpose, we offer the DKDP (KD*P) series and LiNbO3 series Pockels cell.
You can operate the cell with either a pull-up voltage or a pulldown voltage. Changing the polarity will only change the direction of the phase rotation. In other words, the pull-down voltage Q-switch use ª-/4-voltage pulses on the Pockels cell and the pull-up voltage Q-switch use ª-/2-voltage pulses on the Pockels cell. You should not, however, operate the cell with a constant applied voltage potential between the terminals, or a duty cycle greater than ~ 2%.

Fujikura fsm-60s fusion splicer is a updation of fujikura fsm-50s fusion splicer, 60s machine sets the standard for core alignment fusion splicing by incorporating a user-friendly interface with enhanced features to provide the most rugged and reliable fusion splicer in the market today. The new rugged construction adds improved reliability by resisting shock, dust, and rain, and can withstand a 30" drop test.
The fsm-60s splices a optical fibre in 9 seconds and heats a 60mm splice sleeve (heat shrinkable tube)in 30 seconds, for a total cycle time of only 39 seconds. New features, such as automatic tube heater operation, user-selectable clamping method (sheath clamp or fibre holder system), automated monitor tuolima image orientation, and battery charge capability during splicer operation provide the end user a productivity tool they can count on.

A water-cooled acousto-optic Q-Switch for use in high-power Nd:YAG laser systems. Combining top grade fused silica with high quality optical finishing and in-house anti-reflection coatings, this Q-Switch exhibits very low insertion loss and high damage threshold. Through an innovative design and manufacturing process, RF powers up to 100W may be applied.
Standard options include a choice of frequencies (24 to 68MHz), active apertures (1 to 8mm), acoustic modes (compressional for linear polarisation, shear for unpolarised) and water connectors. Customised housings are available for OEMÆs.
A high power RF driver module is available in output powers of 50W, 75W or 100W. Powered from 220VAC or 110VAC, the modulation inputs allow either full digital control or activation of an internal pulse generator. First pulse suppression is automatically implemented.
