Supplier: Visual Sound, Inc.
Description: ' lamp mode High Installability Lens center layout (symmetry) A symmetrical design with the lens in the center of the projector has been adopted to suit ceiling installation in particular. This allows the projector and the screen to be centered together, which not only makes design
Description: Rabbit polyclonal Crystallin Gamma C antibody raised against the middle region of CRYGC Background: Crystallins are separated into two classes: taxon-specific, or enzyme, and ubiquitous. The latter class constitutes the major proteins of vertebrate eye lens and maintains the transparency
Supplier: Premier Lighting & Production Company
Description: With its wave lens design and easy focusing knob, the PARnel lets you quickly access a range of 25 to 45 degrees - a smooth, soft, symmetrical field that you can spot or flood like a fresnel. Features an enhanced aluminum reflector. Rated up to 750w. Comes w/color frame. Shipment subject to stock
Description: The WLA5 Step Light is a recessed wall fixture featuring a water tight polycarbonate lens. The wide light pattern is ideal for critical lighting applications like walkways and stairs where safety is paramount. The copper-free die cast aluminum WLA5 will not oxidize, and the fixture is finished

Saint-Gobain Surface Conditioning Group
Ophthalmic Market, Polishing Lens Compounds
Saint-Gobain Ceramic Materials' Specialty Abrasives group has launched a new line of plastic lens polishing compounds for the ophthalmic industry to polish MR lens, polyurethane lens and polycarbonate lens. Our patented plastic lens slurries were first proven to be effective on conventional polishing machines that rotated in symmetrical and spherical motion until the desired optical surfaces were achieved. We have also developed a line of polishing compounds suitable for Freeform optical... (read more)
