Quartz Tungsten-Halogen Lamp




  • Broadband Emission from Visible to NIR
  • SM2-Threaded Housing for Compatibility with Ø2" Lens Tubes
  • Post Mountable for Quick and Simple Integration

Features

  • Broadband Emission from 400 - 2200 nm (See Specs Tab)
  • Internal SM2 (2.035"-40) Threads Compatible with Our Ø2" Lens Tubes
  • Bottom-Located 8-32 (M4) Tap for Ø1/2" Post Mounting
  • Adjustable Bulb Height
  • Includes Condenser Lens, SM2-Threaded End Cap, and Universal Power Supply

Thorlabs' Quartz Tungsten-Halogen Lamp is a versatile general-purpose light source for alignment, testing, and illumination needs. Packaged in a compact Ø2.20" (Ø55.9 mm) housing with a built-in heat sink, it contains internal SM2 (2.035"-40) threading on both sides for direct compatibility with our Ø2" lens tube accessories, as well as an 8-32 (M4) tap for use with our Ø1/2" posts.

With broadband emission in the visible and NIR spectral ranges (as shown in the graph within the Specs tab), this incoherent light source is ideal for aligning a wide range of setups without introducing laser light. It can also be used in combination with a CCD Spectrometer to characterize lenses, filters, or other optical elements.

This white-light lamp ships ready for use with an externally SM2-threaded end cap (SM2CP2) and a condenser lens (ACL5040) that has been mounted in an SM2 lens tube using an SM2RR retaining ring. A setscrew that accepts a 0.05" hex key (included) is exposed when the end cap is removed, allowing the bulb's height to be adjusted to maximize imaging quality and light collection without having to remove the condenser lens or other attached optics. For a typical output beam profile, please see the Specs tab. To power the bulb, a universal power supply (90 - 264 VAC) with plugs for all regions is included.

Please note that the lamp should not be operated without the end cap and condenser lens, as the bulb's surface will be hot to the touch. After warming up, the heat sink will reach a temperature of 50 °C.

If your application would benefit from a fiber-coupled output, stabilized output power, or a stabilized spectrum, please consider our fiber-coupled broadband light sources.

  • Measured by focusing the output beam after the ACL5040 condenser lens onto an S302C thermal power sensor with an MPD508762-90-P01 protected silver off-axis parabolic mirror.
  • We strongly recommend wearing gloves (such as our MC6 cotton gloves) when replacing the bulb in order to prevent skin oils from being deposited on the glass. If you suspect the bulb is dirty, carefully clean it with alcohol before connecting to power.
