Although a common misconception, individual optical lenses do not always form an image when the object plane is placed a focal length away from the lens.
Meniscus lenses offer superior performance compared to plano convex lenses in IR applications. Find out the benefits of using a meniscus lens at Edmund Optics.

Learn how Highly-Dispersive Mirrors compensate for dispersion and compress pulse duration in ultrafast laser systems, which is critical for maximizing performance.
Mounting flat mirrors by their edges in a kinematic mount imparts stress onto the mirror surface. This results in distortion and reduced quality of the reflected wavefront, which is especially noticeable when using high-quality mirrors. Stemmed mirrors, on the other hand, are mounted from a smaller diameter “stem” protruding from the back of the mirror, resulting in significantly reduced stress on the mirror surface, high stability, and cost reduction and can be used as a replacement for a more expensive and complex kinematic mount and a conventional mirror.
Cinema lenses designed to create content tailored for online streaming utilize aspheres to shoot with a shallow depth of field while maintaining quality.
Single-Material Aspheric Achromats correct chromatic aberrations with a unique geometry, leading to numerous benefits over conventional achromatic lenses.
Telecentric Lenses can grow quite large and heavy with small magnifications, as such magnifications require large front optics. Learn more at Edmund Optics.
Fresnel lenses are composed of a series of concentric grooves etched into one side of a sheet of plastic. Fresnel lenses are unlike typical spherical or aspherical optical lenses.
