Norland’s optical and electrical UV adhesives allow fast accurate tacking, simplifying processes that require critical alignment or exact positioning.

Aspherical lens photography

Norland manufactures different products including ultraviolet curing optical adhesives, UV curing electronic adhesives, fiber optic equipment, and fish gelatin. Most of their products are unique and offer high-performance properties with definite advantages over alternative products in the marketplace.

3. An aspherical lens element has much more precise control of how light travels inside your lens. So much so, that one asphere can oftentimes negate the need for many of the standard lens elements that would otherwise be needed to achieve the same effect.

AsphericIOL

Aspheric lenses are designed to reduce spherical aberration and other optical aberrations, leading to enhanced image quality and reduced optical distortion.

An aspherical lens is simply a lens that doesn’t have a spherical surface shape. Instead, it has an aspheric surface (i.e. non-spherical), usually with counter-curves near its edges.

As you can imagine, aspherical lenses aren’t just used in cameras. They’re a vital part of any system that needs a high standard of optical quality, from telescopes and contact lenses, to rifle sights and missile-guidance systems.

Standard lenses use spherical elements, many of which aren’t natively able to direct the light reaching its edges to the same focal point as the light reaching its center.

What is asphericglasses

Either way, knowing what an aspherical lens is and what it does will help you in better understanding your gear and when it comes time to purchase new types of camera lenses, you’ll have a better idea of what to buy.

Asphericlenses advantages disadvantages

Optical Adhesives: Norland’s one-part adhesives will set in seconds to ultraviolet light, and provide excellent light transmission. Their optical glues are designed for bonding where low strain, optical clarity or low outgassing are required in military, aerospace, fiber optics or commercial optics.

Ideally, light rays, when passing through a camera lens element, would all converge at a single point thereby creating a sharp focus. Unfortunately, this isn’t the case with many spherical lenses.

Learn about the benefits of aspherical lenses (Asph Lens) in photography and why you should (or shouldn't) attach one to your camera in 2023.

Absolutely! They’ll make your lens lighter, your images sharper, and bring aberrations and distortion down to near zero. The only downside is how much they cost.

One way to compensate for this is by using a combination of concave and convex lens elements. Another way is by using an aspheric lens.

It’s really amazing how far modern optics have come. Not too long ago, only pros could afford full-frame cameras and aspherical lenses. Now those of us in the prosumer world can get them too.

They also allow manufacturers to create smaller and lighter lenses since they reduce the need for numerous lens elements and lens groups.

1. Physically, spherical lenses have a front surface that is spherical, meaning the curve is the same from top to bottom and left to right – like a portion of a sphere.

Aspherical lenses are used primarily in high-end optics to create sharper images and reduce or eliminate certain optical imperfections (i.e. chromatic aberrations, field curvature, etc.).

These counter-curves direct light rays hitting the edges of a lens to converge at the same point of focus as the light rays hitting the center.

Of course, asph lenses are considerably more expensive than spherical lenses, but high-quality glass will last a lifetime, so if you can spring for the high-performing lens, go for it!

Spherical aberrations occur when incoming light rays pass through a spherical lens and focus at different points, causing blurry images and reducing overall image quality.

The aspherical glass lenses used in top-of-the-line telephoto and wide-angle lenses are particularly expensive. They’re usually ground and polished by hand.

The lens surface of an aspherical lens corrects for this, making it possible to shoot at wider apertures and allowing us to use the entire surface of the lens.

Asphericlens benefits

Designers – especially with wide-angle lenses – often have to stop-down their optical systems to exclude the corners so as to avoid an excess of field curvature.

Electrical Adhesives: These one-part adhesives set in seconds with UV light or cure with heat to form an electrically insulating bond to fasten, tack or fill. Areas not exposed to UV light can cure because of a latent heat catalyst.

Maybe you’re looking at buying a new lens and aren’t sure if you should fork out the extra cash for the one marked “Asph Lens,” or you’re just wondering what makes aspheric lenses expensive.

In the past, only pros could afford such top-of-the-line optics. These days they’re still spendy, but at least they’re not completely the ballpark for ordinary photographers.

Aspherical lenses are curved outwards on their rear element so that they can better direct light rays into a single focal point. These counter-curves help correct spherical aberration, creating sharper images.
