Broadband AR Coated Achromatic Lenses(Doublet Lenses)

Achromatic Lenses are used to minimize or eliminate chromatic aberration. The achromatic design also helps minimize spherical aberrations. Achromatic Lenses are ideal for a range of applications, including fluorescence microscopy, image relay, inspection, or spectroscopy. Achromatic Lenses, which are often designed by either cementing two elements together or mounting the two elements in a housing, create smaller spot sizes than comparable singlet lenses.

6.1.What do you mean by achromatic combination?

An achromatic lens can be defined as a lens which is made by acombination of two different types of lenses carrying different focal powers in a manner such that the images formed by the light of both the combined lenses are free from chromatic aberration or achromatism.


6.2.What are achromatic lenses used for?

Achromatic Lenses are used to minimize or eliminate chromatic aberration. The achromatic design also helps minimize spherical aberrations. Achromatic Lenses are ideal for a range of applications, including fluorescence microscopy, image relay, inspection, or spectroscopy.

Rod Lenses are used for fiber coupling and laser diode beam shaping, lenses with a 0mm working distance are ideal for collimation of single and multi-mode optical fibers and laser diodes because the lens can be positioned and glued directly to the emission source. For focusing applications, or in instances where the lens can’t be in direct contact with the emission source, all lenses are available with a small working distance as well. HG OPTRONICS  can provide the size from Φ1~Φ15mm, quantity price and custom sizes, including variations in polished/ground surfaces, are available to customers upon request.

Ti:sapphire laser crystals
Ti:Sapphire Crystal Titanium Doped Sapphire

Ti:Sapphire crystal is the most widely used tunable solid-state laser material combining the supreme physical and optical properties with the extremely broad lasing range. Its lasing bandwidth can support pulses < 10fs making it the crystal of choice for femtosecond mode-locked oscillators and amplifiers. The absorption band of Ti:Sapphire centers at ~ 490 nm so it may be conveniently pumped by various laser sources such as argon ion lasers or frequency doubled Nd:YAG, Nd:YLF, Nd:YVO4 lasers at ~530nm. Laser designers are using Ti:sapphire to generate femtosecond pulses to create new industrial tools. A properly delivered femtosecond laser pulse interacts within the target leaving the surrounding area undisturbed. Newly developed femtosecond pulsed lasers micro-machine complex fine structures in glass, metal and other materials. Active waveguides can be written below the surface, integrating optical devices within the body of a substrate. Defects in photomasks can be repaired without disturbing neighbouring patterns. And it is now possible to achieve cellular resolution in vivo for medical diagnosis with femtosecond pulse lasers.
