The HL-2000 Tungsten Halogen Light Sources are versatile lamps optimized for the VIS-NIR (360 nm-2000 nm). The lamps feature adjustable focusing of the SMA 905 Connector to maximize light coupling into a fiber. A fan keeps the light sources cool and stable. A built-in filter slot accepts optical filters up to 25.4-mm round or up to 50.8-mm square and up to 3 mm thick. All HL-2000 Light Sources come with an efficient regulated power supply.

HL-2000 Features

• Long-lifetime Option. Source available with 10,000-hour bulb

• High-power Version. Doubles your output power

• Great Versatility. Fan-cooled, with shutter, TTL and manual attenuator functions

• RS-232 Interface Option. Access shutter and attenuator via RS-232 interface

The HL-2000, available for $750, comes with a 1,500-hour bulb, and a long-life (10,000-hour) version is also available. Additional HL-2000 models are also available.

Shutter Option

A manual and TTL shutter on the HL-2000-FHSA version of the HL-2000 allows you to attenuate the intensity of the light source.

High-power Version

For applications requiring large-diameter optical fibers or fiber and probe bundles, a special high-power version of the HL-2000 is available. The bulb used in the HL-2000-HP is a 20-watt bulb. In addition, you can opt to control the intensity of the HL-2000-HP via an RS-232 module. This option allows you to control the intensity from 0-100%, as well as to control the shutter.
