KL 2500 LCD - The Benchmark in Performance

KL 2500 LCD
With its new design and unique performance spectrum, the KL 2500 LCD is setting a new benchmark in the field of halogen cold light sources. Fittted with a 250-watt cold light reflector lamp, the KL 2500 LCD transmitts more than twice the amount of light as the KL 1500 LCD. This unparalleled performance makes the KL 2500 LCD the instrument of choice for the most chanllenging applications in Stereo Microscopy, Macroscopy and Forensics.
The KL 2500 LCD is equipped with a 5-position filter wheel, which makes filter selcection quick and easy. Color filters and special GFP-fluorescence excitation filters are also available. Electronic accessories such as remote control or tilt switch can be connected to the analog socket in the front panel, enabling remote light source operation or connection of an RS-232-Interface.
The KL 2500 LCD has been approved and certified as laboratory and electromedical device by VDE (230 volt version) and CSA (C/US) (120 volt version). The 230 volt version carries the CE conformity label.

A broad range of fiber optic light guides as well as a selection of color filters, polarizers and focusing accessories completes the offering.

The KL 2500 LCD accepts light guides with bundle diameters up to 15 mm (.6"), evenly illuminated with the ELC-type halogen lamp. The larger bundle diameters in combination with the 250-watt lamp power enable demanding applications as GFP fluorescence microscopy or short exposure macro-photography as well as light demanding incident darkfield illuminations.
