02 Nov 2010 If you require a line with a homogeneous distribution of intensity then you can use a diffractive optical element. Our partner Holo/Or has included a new standard DOE in its programme, featuring high transmission and an excellent diffractive efficiency.
Two 1 x 81 spot elements were developed with a 10° and 25° fan angle for 532nm. This results in a separation angle between each of the two adjacent beams of 0.12° and 0.25°.
These elements are available both for other wavelengths and in other materials, such as, for example, sapphire. The separation angles vary depending on the wavelength.
Properties and Applications
Overlapping individual spots guarantee the generation of a homogeneous line. This line is not position sensitive, but is tolerant regarding the quality of the input beam. For example, a 2 x 80mm line can be produced with a 2mm input beam at a working distance of about 230mm.
