OPTICS

The Dapromat diffractive hybrid apochromatic lens from Melles Griot (Irvine, CA) uses diffractive optics technologies to achieve a milestone in multiwavelength focusing performance. Aprochromatic lenses permit three wavelengths--red, green, and blue--to be focused to the same point, making them useful for broadband light-source applications. Introduced in July 1995 and available with focal lengths from 16 to 100 mm, Dapromat lenses offer diffraction-limited performance from 480 to 780 nm; their

Aprochromatic lenses permit three wavelengths--red, green, and blue--to be focused to the same point, making them useful for broadband light-source applications. Introduced in July 1995 and available with focal lengths from 16 to 100 mm, Dapromat lenses offer diffraction-limited performance from 480 to 780 nm; their design also reduces chromatic and spherical aberration. Designed to withstand high-energy laser throughput, the lenses eliminate refocusing when using multiwavelength or tunable lasers, which saves time, reduces costs, and simplifies systems.
