Using two achromatic lenses as a pair can achieve excellent performance in imaging applications. The TECHSPEC Achromat Prototype System allows for experimentation with different focal length ratios to obtain various magnifications and actual field sizes. The camera sensor and subject are positioned at the focal points on both the image side and object side of the two achromatic lenses used. The lens's F-number can be adjusted by changing the aperture size using the aperture kit included with the achromat prototype kit. At this time, the aperture is used between the two achromatic lenses (the aperture is not threaded). For more details, please refer to the product page on the official website of Edmund Optics Japan. ■ For prototyping imaging lens systems ■ Ideal for identifying required magnifications and F-numbers ■ Compatible with C-mount cameras using the included C-mount helicoid barrel *The catalog from Edmund Optics Japan can be downloaded from the link below.

Two 25mm diameter near-infrared achromatic lenses have been assembled inside a Φ30x34mmL tube to create a relay lens optical system (unit conjugate ratio design). Based on the focal length ratio of the two lenses, various combinations of magnification ratios and F-numbers can be selected. Note that lenses with low F-numbers may not be suitable for imaging applications (this also depends on the required performance level). For focusing adjustments of this product, using a T-mount focusing barrel is convenient. ■ 30mm diameter tube lens designed for near-infrared applications ■ Optimized for various magnification ratios ■ Ideal for integration into OEM applications ■ Each lens features NIR II multi-AR coating effective from 750 to 1550nm * The catalog from Edmund Optics Japan can be downloaded from the link below.

Edmund Optics offers a wide variety of achromatic lenses. We provide multiple anti-reflective coating options for ultraviolet (UV), visible, and infrared (IR) applications, including UV-VIS, MgF2, VIS 0°, VIS-NIR, NIR II, and SWIR. Additionally, we have achromatic lenses specifically designed for ultraviolet (UV) and infrared (IR) applications. The same lenses for ultraviolet (UV) and infrared (IR) offer superior performance compared to standard achromatic lenses coated for the same or comparable wavelength ranges (designed for the visible spectrum). Aspherical achromatic lenses combine the color correction capabilities of achromatic lenses with the excellent spherical aberration correction capabilities of aspherical lenses. Triplet achromatic lenses are available for applications requiring a 1:1 conjugate ratio or high magnification. For more details, please visit the official Edmund Optics website via the link below.

This document explains the reasons for using achromatic lenses. It introduces various types of achromatic lenses, such as positive types with a positive focal length, negative types with a negative focal length, as well as triplet types and aspherical types, along with noteworthy performance characteristics. When compared to singlet lenses with the same diameter and focal length, there are numerous advantages that achromatic lenses offer which are not present in singlet lenses.
