Is LED good for photography?

LED has become one of the most popular choices of continuous light for photography as they don't produce a lot of heat and closely replicate the feeling of natural light with their adjustable colour temperature.

What is a double convex spherical lens?

Bi-Convex (Double-Convex) lenses have the same radius of curvature on both sides of the lens and function similarly to plano-convex lenses by focusing parallel rays of light to a single point. ... Bi-Convex lenses are the best choice when the object and image are at equal or near equal distance from the lens.

How double convex lens work?

A double convex lens, or converging lens, focuses the diverging, or blurred, light rays from a distant object by refracting (bending) the rays twice. ... This double bending causes the rays to converge at a focal point behind the lens so that a sharper image can be seen or photographed.

What is application of double convex lens? 

Double-Convex Lenses are used in image relay applications, or for imaging objects at close conjugates. Double-Convex Lenses have positive focal lengths, along with two convex surfaces with equal radii. ... 

Specifications of double-convex lens we can provide

 VY Optoelectronics Co.,Ltd. offers large inventory of off-the-shelf optical components, which includes a large variety of Bi-Convex Lenses. VY Optics’Bi-convex lenses are available in a range of coating or substrate options. Anti-reflection coatings range from the Ultraviolet (UV) to the Infrared (IR), including UV-AR, UV-VIS, MgF2, VIS 0°, VIS-NIR, NIR I, NIR II, or Telecom-NIR. Additional coatings designed specifically for laser wavelengths, such as 266nm, 355nm, 532nm, or 1064nm are also offered. Germanium (Ge), Silicon (Si), or Zinc Selenide (ZnSe) substrates are ideal for Infrared (IR) applications.

 VY Optics can also manufactures Plano-convex lenses according to you specication, material has wide range, from S1-UV Grade Fused Silica, G1 Fused Quartz, Commercial Grade, and BK7 Optical Glass. Every optic is pitch polished, providing good surface quality and an exceptional low-cost imaging performance with a variety of light sources.

We also offer plano-concave lenses, which have negative focal length components and one concave surface. For information on our optic lens custom work, contact VY immediately.

People also ask

• What is difference between convex lens and double convex lens?
  A plane convex lens is plane on one side and convex on the other side; while the biconvex or double convex lens is curved in convex manner on both sides of the glass, as used in magnifying glass.
   
• Can you use a double convex lens in a telescope?
  Most simple telescopes have two convex lenses. The objective forms a case 1 image that is the object for the eyepiece. The eyepiece forms a case 2 final image that is magnified.
   
• How does light travel through a double convex lens?
  Second generalization for the refraction of light by a double convex lens can be added to the first generalization. 
  Any incident ray traveling parallel to the principal axis of a converging lens will refract through the lens and travel through the focal point on the opposite side of the lens.
