ME-Optics Selection Guide
The lens or a combination of these lenses found in this section will have limited applications compared with single spherical lens but very high performance can be achieved in a dedicated application.
|Achromatic Lens||Chromatic and spherical aberration is minimized.
Large line-up of focal length and aperture.
|Focus ability in low power lasers.
Imaging system for infinity object
|Focusing Lens||High laser damage threshold
Spot size is minimized and near to the diffraction limit.
|Lens for various laser fabrication such
as laser marking, cutting and welding.
|Objective Lens||Highly corrected lens with high magnification
Large numerical aperture produces minimum spot size.
Fully usable throughout the visible wavelength spectrum.
|Microscopic imaging for the visible,
ultra-violet and near infrared
Focusing a laser beam into a minimal spot.
Micro-fabrication for lasers.
|Beam Expander||Optimized design for minimum spherical aberration
Integrated design with reduced size
|Magnifying the laser aperture
(for interferometer and projection)
Reducing the focal spot size
(by enlarging the incident laser beam diameter)
+ Achromatic lens
|Large choice of expansion ratios.
Provides a high purified beam profile.
|When using a very large collimated beam.
When changing the beam aperture
(with switching the achromatic lenses)
