Accessories for laser diode control

• Improves temperature stability
• Works with 203, 205, and 207 mounts

The laser cover is an excellent way to improve the thermal stability of the laser by shielding it from the air drafts that can otherwise cause small shifts in plate and device temperature. For applications that require the highest level of temperature stability, the 200-C cover is an excellent addition. The cover works with the 203, 205, and 207 mounts, and can also be used in-conjunction with the 200-TRAY fibre management tray.

The cover can be screwed down or simply set onto the mount. Alignment pins built into the cover will prevent it from sliding around.

• Significant thermal performance improvements for the 203 & 205 mounts
• Quick upgrade

The 200-FAN fan base is an option for the 203 and 205 LaserMounts for applications that require greater thermal performance. By using a small fan to force air across the mount’s heat sink, the efficiently and performance of the mount is significantly increased. For the 203, this means a thermal performance increase from 2.3°C/W to 1.0°C/W, while the 205 has an increase of thermal capacity from 3W to 8W.

Installing the fan base is easy. Simply remove the 4 screws from the bottom of the mount, replace the standard base plate, and screw on the new fan base.

• Quick, easy fibre management
• Works with 203, 205, and 207 mounts

The fibre management tray is an ideal solution for managing excess fibre on pigtailed laser diodes. The fibre tray works with the 203, 205, and 207 mounts, and can also be used in conjunction with the 200-C cover.

By using the natural tendency of the fibre to uncoil, the fibre tray will capture the fibre without the need of ties or other restraints that could otherwise damage the fibre.

• Improved thermal stability
• Nitrogen purge fitting
• Can be bolted to mount
• Protection against direct laser exposure

Improved Thermal Stability
Air currents can have a significant impact on thermal stability, particularly with large cold plates like the 264. For applications that need a very stable reponse, the 260-C is a custom designed cover that fits snugly on top of the fixture, and can be bolted down to prevent removal.

Nitrogen Purge Fitting
The 260-C also includes a 1/8″ barbed nitrogen purge nipple to purge the cavity to prevent condensation when operating below the dew point.

• Fast response time
• 10k Ω at 25 °C
• ±0.1 °C accuracy from 0 to 70 °C

The 1600-10K is an accurate 10kΩ epoxy coated bead thermistor, identical to the thermistors used in most Arroyo Instruments mounts. Accurate to ±0.1°C from 0 to 70°C, this high performance thermistor works well in many applications. The thermistor is very fragile, and should be secured into position with thermally conductive epoxy or similar bonding compound. We offer 1601 Thermal epoxy, a 2-part epoxy packaged in 3 gram packets.

• Fast response time
• 100 Ω at 0 °C
• ±0.12 % (±0.33 °C) at 100 Ω

The 1600-100RTD is an accurate 100Ω platinum RTD, identical to the RTDs used in Arroyo Instruments’ high temperature mounts. Accurate to 0.12% (±0.33°C) at 100Ω;, this high performance RTD works well in many applications and across a wide range of temperatures. The RTD is encased in a small stainless steel housing, and should be secured into position with thermally conductive epoxy or similar bonding compound. We offer 1601 Thermal epoxy, a 2-part epoxy packaged in 3 gram packets.

It is a switching power supply, and will work on any standard worldwide voltage.
