KL Fiber Optic Light Guides

SCHOTT’s KL Fiber Optic Light Guides offer modular fiber optic illumination for stereo microscopy and are the ideal match for our KL Light Sources. Made using high quality PURAVIS® glass fibers in a tough metal housing, they deliver strong performance, superior longevity and outstanding transmission of white light.

Broad product portfolio

A large variety of light guides offer the flexibility to realize all common illumination techniques. Specialist light guides such as SCHOTT’s Line Light also emphasize the adaptable nature of our system, while the combination of light source and guide offer optimal contrast for an individual sample.

High white light transmission

All SCHOTT microscopy light guides use PURAVIS® glass optical fibers to offer high light transmission and low color shift. And thanks to an improved numerical aperture, the light guides capture more light at their source, leading to a brighter, more intense output.

      Replacements / Spare Parts

      Light sources such as the KL 1500, KL 1500 electronic, KL 1500 compact, KL 1500 LCD, and KL 2500 LCD or the ColdVision ACE® and DCR® III are not available anymore. Please take a look at the table to see which new model might work for you as replacement.

      Table showing the specifications of a range of SCHOTT light sources

      Light bulbs for our old light sources are still available. However, other spare parts are not available anymore for old light sources such as the KL 1500, KL 1500 electronic, KL 1500 compact, and KL 1500 LCD. 
      A halogen light source can only be used with a halogen lamp. LED modules are not available.
      A replacement is possible. However, halogen and LED light sources have different characteristics, so check before if your application can accept limitations in color reproduction, especially in the bluegreen and red color range. For more details, see the tab "LED vs Halogen".

      Compatibility of products

      The light guides of a KL 300 LED cannot be used with a KL 1600 LED, KL 1500 HAL, or KL 2500 LED. The connections are not the same. Only light guides for the KL 1600 LED, KL 1500 HAL, or KL 2500 LED can be mounted to a KL 1600 LED, KL 1500 HAL, or KL 2500 LED. For a full overview of compatibilities see our system diagrams.
       
      The light guides of a KL 2500 LCD cannot be used with a KL 2500 LED. The KL 2500 LCD uses special light guides with active fiber bundle diameters of 12 and 15 mm. Therefore they are not compatible with a  KL 2500 LED. For a full overview of compatibilities see our system diagrams.
      Our ring lights are mounted directly to the objective of the microscope. Depending on the diameter of the objective, we have ring lights with inner diameters of 40, 58, 66, 80, 81, 85, and 86 mm, as well as adapters for the 66 mm ring lights for 60, 58 and 50 mm. Take a look at our Adapter Selection Guide (Download Pdf) to see which adapter is required.
      To use light guides from other manufacturers, we offer a wide range of adapters. For more details see our system diagram, ask your reseller, or contact us.

      Can I still use halogen lamps or are they forbidden?

      On 1 September 2018, the EU regulation 244/2009 came into effect, which prohibits the placement of specific inefficient and non-directional household lamps on the market. However, this ErP directive 2018 explicitly excludes special lamps such as projection lamps, which relates to the used lamp in KL 1500 HAL. These can still be produced and sold.

      Differences of products

      A diffusor softens the light and reduces the reflection of LEDs on the sample. A polarisation filter eliminates reflections from the surface of the sample and pronounces anisotropic materials, but can also change the impression of the image. Furthermore, this method is very light-consuming.

      The Gooseneck is a flex-and-stay light guide which will remain in place after positioning. The flexible light guide does not stay in place and needs to be held.
