Multifocal literally means “having more than one focus” so bifocal and trifocal lenses are actually types of multifocal lenses. In addition to bifocal and trifocal lenses, the other multifocal is a progressive addition (no-line bifocal) lens that increases in power from the top to bottom of the lens. Progressive lenses have no clear dividing lines as the focus changes from bottom to top. Progressive addition lenses avoid the “image jump” in the visual field created by bifocal and trifocal lenses and are more cosmetically attractive.

Just like ordinary clear lenses, original Transitions lenses are clear when indoors and at night. Once outdoors, these lenses conveniently adapt to varying light conditions and become darker in either grey or brown activated color options. These everyday lenses provide continuous comfort and peace of mind by decreasing glare, reducing eye fatigue and blocking 100% of UV rays. This lens option is ideal for kids too!

Note: A ±5V power supply, such as the Hamamatsu C10709 (#84-956), is required for operating the H12402 and H12403 series Micro PMT Modules. PMT Modules are extremely light sensitive and exposure to ambient room light during operation will permanently damage the module. Housings are also fragile and will be permanently damaged if dropped. Damages due to above reasons are not covered under warranty or return policies.

The gray, smoke or green lenses are the most popular because not only do they cut the bright light but they also help keep the colors appearing the most natural and true. Polarized lenses can also be used indoors by those persons with light-sensitive eyes or those exposed to bright light through windows or while on the computer.

Bifocal lenses have two parts: the upper part normally used for distance vision and the lower part used for near vision tasks such as reading. Many people after reaching age 45 develop a condition called Presbyopia, which is a deterioration in the ability of the eye’s natural lens to expand or contract in order to focus on close objects. People with Presbyopia need a special lens for reading and may need a different lens for seeing in the distance.

Polarization is a contrast enhancement technique that can reduce back reflections and bring out features not readily visible with normal viewing. Polarized Lenses eliminate glare. Any surface can create glare in sunlight, including water, sand, snow, buildings, windows and vehicles. They can, in fact, reduce the glare that comes off a long, flat surface such as the hood of a car on the highway.

Hamamatsu Micro Photomultipler Tube (PMT) Modules combine a micro PMT, a voltage divider circuit, and a high-voltage power supply into a small form factor. These Micro PMT Modules use the same vacuum tube technology as conventional PMT Modules and are capable of delivering the same performance as conventional PMT modules. Hammatsu Micro PMT Modules are used in flow cytometry, Raman spectroscopy, semiconductor wafer inspection, medical, and environmental testing applications, particular those involving space sensitive device designs. Micro PMT Modules are available in an upright configuration (H12403 series) or flat configuration (H12402 series) and provide spectral response between 300 - 920nm.
