The newest single lenses from Khatod, able to provide a superior clean rectangular beam, are high efficiency lenses designed for use with the most popular existing LED references of the latest generation.

Most lenses for LED applications in current use deliver output beams with circular or elliptical profiles. The light distribution as well as the intensity they produce is mostly suitable for applications in which a small spot is focused by the light beam.

However, a uniform intensity distribution focused to a wider and not circular pattern, often referred to as a "flat-top," is increasingly required in many different uses.

As an example, the inspection lines of material processing departments require a wide rectangular spot of light that has a perfect and uniform light intensity distribution. This will ensure that the entire illuminated area is perfectly processed and controlled.

The rectangular spot is used essentially for illumination and not for focusing a single individual point. For this reason, it is essential that the illumination is uniform, and any point in the rectangular light pattern needs to have the same features of brightness, regardless of where it is located in the illuminated field.

Thanks to Khatod’s most advanced optical technology, the PL1672 lens is able to produce a perfect rectangular beam. The toroidal lenslet array creates a rippled surface able to reshape the light into a beam whose size is the one of an A4 paper sheet (~300×200 mm2, 12×8 inch2) at 1 m distance. The distribution in the light pattern is totally uniform.

These characteristics cover a wide range of applications that can be generally classed as "illumination." They may range from lighting in a museum to desk lamps or inspection lines as explained above.

Khatod Rectangular Beam Lens is currently available in 35.0 mm diameter.

On request, this lens is also available in different diameters, i.e. ∅ 50.0mm and ∅ 46.8m. The optical characteristics will remain the same.

The mounting onto the LED is easy and immediate: 3 pins on the lens bottom allow precise and robust mounting.
