The ELS-250, fiber optic illuminator, is ideal as a heat free perfect white light source for many applications like;

• Machine Vision
• Surface Inspection
• General Microscopy
• Fluorescence Microscopy
• Other technical lighting application

The ELS-250 is based on the electrode-less technology driven by a solid state RF (radio frequency) amplifier to eliminate the primary degradation mechanism associated with HID lamps. Without electrodes in its design, the ELS-250 can offer extremely long life and unprecedented reliability in technical lighting applications. It excess over 10,000 hours of lamp life while a typical metal halide system only last up to 2,000 hours of lamp life.

High Brightness

*Actual values observed 100mm from the end of the collimator lens via hybrid light guide
(active core Dia. 10mm)

High Stability

Low flicker in intensity over long hours of operation results in better signal to noise ration in imaging applications.

Spectral Output

*The spectral output shown on the graph were obtained via 8mm diameter core liquid light guide.

The ELS-250 produces a perfect continual spectrum in VIS region, 400nm to 750nm. Heat transfer is eliminated by its nature of spectrum from the electrodeless lamp that does not emits IR radiation.

Color Rendering Properties

Ideal for technical lighting applications where high CRI is required for accurate color rendering of illuminated objects.

User friendly menu and comprehensive display for easy unit operation and maintenance.

• Lamp ON/OFF
• Shutter Activation OPEN/CLOSE
• Light Intensity Adjustment(30 to 100%)

*All of those features can be controlled remotely by using RS232C.

Light intensity can be quickly and reliably set from 30% to 100%. You can easily set the desirable percentage with the digital panel of the main unit just by pressing UP and DOWN buttons.

The ELS-250 is also equipped with an internal shutter which activated by button or RS232C commands.

Asahi Spectra produces many varieties of precise optical filters to help modification of spectral output. You can select the filters from our optical filters page to fit your application.

This filter holder holds;
-50x50mm
-Φ50mm
with thickness between 1.0mm to 7.0mm

The illuminated light is delivered to the illuminated area via fiber light guide. We recommend to use ELS-250 with our original light guides but it is also compatible with most major light guides with optic fiber adapter. Please contact us to discuss your adapter needs prior to purchasing.

General Application;

Microscopy Application;

Collimator lens reduces the divergence of light from the light guide and provide uniform light output. It is suitable for directional backlighting which requires clear silhouette of an object.
