Overview

Fabricated out of B270 or equivalent glass, and featuring a single-layer visible MgF₂ antireflection coating, these condenser lenses provide excellent transmission in the visible region. The aspheric condenser lens surface is molded, while the plano or spherical surface is ground and polished. Ideal for light collection, projection, illumination, detection, and condensing applications.

Schott B 270® Ultra-White Glass Substrates

Our aspheric lenses are made from Schott B 270® Ultra-White Glass which has numerous advantages for condenser lenses. For example, it is highly transparent across a wide range of wavelengths, and is highly resistant to intense UV exposure, making it ideal for use with light sources such as high intensity arc lamps.

MgF₂ Visible Antireflection Coating

Our single layer Magnesium Fluoride visible AR coating is the most common choice that offers extremely broad wavelength range at a reasonable price. It is standard on achromats and optional on our N-BK7 plano-convex spherical lenses and cylindrical lenses. Comparing to the uncoated surface, the MgF₂ provides a significant improvement by reducing the reflectance to less than 1.5%. It works extremely well over a wide range of wavelengths (400 nm to 700 nm) at angles of incidence less than 15 degrees.

Advantages of Aspheric Lenses

In applications that require large acceptance angles, such as light gathering for illumination, spherical lenses are unsuitable due to spherical aberration, or the effect of refractive power of a spherical surface becoming greater with increasing aperture. Aspheric lenses maintain constant focal length or very high NA, avoiding the need for multiple elements to correct spherical aberration. This simplifies system design by reducing weight and component count. It also results in less transmission loss, and less ghosting due to having fewer surfaces. The primary drawback of an aspheric lens is off-axis performance is poor. This is not a problem for coupling to and from optical fibers or collimating light sources, but aspheric lenses are not usable over a wide field of view.

Superior Light Collection

Our Aspheric Condenser Lenses provide higher numerical apertures (NA), larger apertures and lower f# ratios, when compared to standard spherical lenses. They are ideally suited for illumination applications, such as light collection and condensing, projection and detection. Examples include coupling light into and out of optical fibers, efficiently collecting output from optical sources, or focusing beams onto small high-speed detectors.

We offer a full range of optical lens mounts to meet various experimental requirements. Below lists the recommended mounts for spherical lenses of standard sizes. Please see our Lens Mount Guide for additional information.

Note: besides the diameter, please check the Edge Thickness (T_e) specification of the lens and the lens mount to ensure compatibility before purchasing.
