From visible light to near infrared, that’s where the AvaLight-HAL-S-Mini works best. The AvaLight-HAL-S-Mini is a compact, stabilized halogen light source with adjustable focusing of the fiber connection, maximizing output power at the desired wavelength. This versatile light source also has adjustable output power to provide extra power or longer bulb life. 

A filter-slot mounted on the front of the AvaLight-HAL-S-Mini accepts 1″ round or 2″x2″ square filters, to block specific ranges of wavelengths or instantly lower the intensity.

The adjustable focus on the AvaLight-HAL-S-Mini helps you get 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.

Optionally, a combined direct-attach cuvette holder and attenuator is available (CUV-ATT-DA-HAL). For attenuation you can use the in-line filter holder (FH-INLINE) or the in-line attenuator (ATT-INL). 

The optical output can be controlled through a dongle at the backside or from your spectrometer. At the lowest setting, the light bulb has a color temperature of 2647K, but provides a significantly longer lifetime. The standard or medium setting changes the color temperature to 2759K and provides around 30% more power with a bulb lifetime of 4000 hours. The high power setting gives a color temperature of 2879K, about 70% more power compared to the long-life setting with a reduced lifetime of the bulb.

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

Update 2020:
We have replaced the bulb of the AvaLight-HAL-S-Mini because of the discontinuation of our previous halogen bulb. The new light bulb has been especially developed to be as close to the previous version as possible. The AvaLight-HAL-S-Mini’s appearance and performance are not affected by this change, so any previously installed bases can still be used, even if the light bulb needs replacement.
