Tungsten Halogen Light Source

VIS/NIR light source
VIS/NIR light source

The AvaLight-HAL-Mini is a visible to near infrared light source.


It’s compact, stabilised and has adjustable focusing of the fibre connection, maximising output power at the desired wavelength. The light source also has adjustable output power to provide extra power or longer bulb life. The adjustable focus on the AvaLight-HAL-Mini helps you getting the most out of your light source - it makes sure all possible power is transmitted through your optical fiber. Bulb replacement is easy and can be done in a matter of minutes.

The AvaLight-HAL-Mini also has filter lot mounted on the front side, which accepts 1” round or 2” x 2” square filters, to block specific ranges of wavelengths or instantly lower the intensity.

As an option, a combined direct-attach cuvette holder and attenuator is available (CUV-ATT-DA-HAL). For attenuation only, one can use the Inline Filter Holder (FH-INL) or the Inline attenuator (ATT-INL).

The optical output can be controlled through a dongle at the rear or from your computer. At low setting the lamp has a colour temperature of 2700K but provides over 13000 hours of lifetime. The standard or medium setting changes the colour temperature to 2850K and provides 50% more power with a bulb lifetime of 4000 hours. The high power setting gives a colour temperature of 3000K, doubles power compared to the long life setting and gives you up to 1000 hours of lifetime.

 The AvaLight-HAL-S-Mini also features an internal TTL-shutter, controllable from your AvaSpec spectrometer. This gives you the ability to use the auto save dark option in AvaSoft spectroscopy software.
