The KL 2500 LED is an innovative fiber optic light source and an attractive alternative to conventional halogen cold light sources. Its high light output and multiple intensity control options combined with an LCD display meet the advanced requirements of all applications of stereo microscopy. Light is generated by nine high brightness LEDs coupled into a slim glass fiber bundle, while heat is managed by a low noise cooling fan. The brightness is equivalent to a 250 W halogen lamp and continuous electronic dimming can be effected from zero to 100% with stable color temperature maintained throughout.
Brightness Equivalent to 250 W Halogen Light Sources
Nine high brightness LEDs, each 7 W, offer illumination that is equivalent to a 250 W halogen lamp. Its high light output and multiple intensity control options meet the advanced requirements of all applications of stereo microscopy. LED energy consumption is lower than with conventional halogen light sources, offering significant cost savings and environmental benefits.
Continuous Electronic Dimming from Zero to 100 %
The KL 2500 LED series enables smooth and continuous electronic dimming from zero to 100 %. This provides the user with ultimate flexibility and control to adjust the illumination to the exact level required for different specimens.
No Color Temperature Shift on Dimming
Color temperature is maintained when the LED is dimmed to any level, thus enabling consistent observation at the optimum illumination.
Slider for Color Filters
The KL 2500 LED incorporates a special slider, which enables use of color and halogen conversion filters for a variety of observational methods and allows simple switching between color and monochrome imaging.
Multifunctional LCD Display
An LCD display shows the brightness setting as a percentage and indicates whether the light source is in "fine-tuning mode" or "rough setting mode" by displaying "FINE” or “COARSE".
Intensity Control at Three Sensitivities
To enable sensitive brightness adjustment in the lower control range or coarse brightness adjustment in the higher control range, the light intensity setting knob can be pressed to achieve fine-tuned control in increments of 0.1 % or coarse-tuned control in increments of 5.0 %. Standard tuning is also available. The brightness can be adjusted continuously by turning the light intensity setting knob.
Foot Switch and Software Control
Illumination using the KL 2500 LED can be switched on and off via a foot switch accessory, which simply connects to the corresponding sockets on the back of the light source. An USB interface allows the light source to be integrated into the OLYMPUS Stream imaging software
Wide range of suitable light guides
The optical system is optimized for coupling the light into one of many available light guides. Depending on the application different types of flexible light guides, gooseneck light guides, ring lights and light lines might fit best.
