Custom Light Guide Capabilities

Dolan-Jenner Industries (Boxborough, MA) offers custom light guide capabilities. The fiber optics are high-intensity and feature a cold light that keeps damaging lamp and infrared heat away from samples and the application area. They also boast a reduced size that allows for greater fiber flexibility in confined spaces and work areas. The custom light guide capabilities feature safe handling and custom mechanical packaging, and can be configured to withstand environmental temperatures from -40°F to 2,000°F.

Laser Diode Driver

The low-noise FL500 Laser Diode Driver from Wavelength Electronics (Bozeman, MT) is compatible with reflow processing less than 250°C. The surface mount chip offers exceptionally low noise laser diode control that can be configured either as two independent 250mA drivers, or as a single 500mA driver. The FL500 can run on a +3V lithium-ion battery or up to a +12V power supply. Its small size, low noise, and modest power requirements make it ideal for hand- held precision laser instrumentation.
