AC254-075-B-ML In Stock

The AC254-075-B-ML by ThorLabs is a top-of-the-line achromatic doublet designed to deliver unparalleled performance in the visible spectral region ranging from 650-1050 nm. This high-quality doublet is computer optimized at infinite conjugate ratios, ensuring that it meets the highest standards of precision. With a diameter of Ø1", the AC254-075-B-ML is pre-mounted in mounts that are threaded and have been engraved, making it a breeze to incorporate into any user setup.

The engraving on the AC254-075-B-ML provides crucial information about the lens, such as its focal length, the antireflection (AR) coating that coats its surface, and the unique part number. The AC254-075-B-ML lens features an arrow that is engraved and indicates the correct way to collimate a point source light. This arrow indicates the direction from a side with a larger bend radius to one with a smaller radius. If aiming at a concentrated light beam, the arrow must indicate the opposite direction of light movement. Additionally, an infinity symbol denotes to the user that lens has a continuously increasing conjugate ratio. The AC254-075-B-ML is designed to be utilized in the near infrared (IR) spectral region and has design wavelength of 706.5 nm, 855.0 nm, and 1015 nm. Additionally, this doublet is handy when it comes to controlling chromatic aberration, which allows a monochromatic source similar to a laser to be utilized to reach a diffraction-limited spot.
