K9 plano convex spherical lens can see the transmittance of near infrared (350-2000nm).
H-K9L (N-BK7) is an optical glass commonly used in the preparation of optical elements.
The collimated beam can converge on the rear focus, or the point light source can be changed into a collimated beam.
Plano convex lenses are ideal for focusing parallel rays at one point. These lenses can be used in a variety of applications. They have proven focal lengths and have near optimal shapes for infinite and finite conjugate applications. The plano convex lens can focus the collimated beam on the back focus, or turn the point light source into a collimated beam

The Fujifilm XF 10-24mm f/4 R OIS Lens is a wide-angle zoom providing a 35mm-equivalent focal length range of 15-36mm when used with Fujifilm APS-C-sized mirrorless digital cameras. A constant f/4 maximum aperture maintains consistent illumination throughout the zoom range and the Optical Image Stabilization system helps to minimize the appearance of camera shake when working with longer shutter speeds. An internal focusing system, and the use of a stepping AF motor, ensures quiet, smooth, and precise focusing capabilities that are ideal for both still and video applications.
Four aspherical and three extra-low dispersion elements are integrated into the optical design to reduce chromatic aberrations throughout the zoom range and to benefit overall image clarity and sharpness. An HT-EBC multi-layer coating helps to minimize ghosting and lens flare for higher contrast and an additional coating has been applied to the rear side of the front-most lens element to further reduce ghosting that is common to lens designs with deep concave elements.
Standard lens featuring superb quality and portability. Two high-refraction lens elements and new Gaussian optics eliminate astigmatism and suppress astigmatic difference. Crisp images with little flare are obtained even at the maximum aperture.
The 40 mm f/2.8G AF-S DX Micro-Nikkor Lens from Nikon is a superb carry-it-everywhere, jack-of-all-trades lens for your Nikon DX camera. The focal length (equivalent to 60 mm in FX or 35 mm format) gives it the versatility to capture portraits, street shots and landscape photos without breaking a sweat. And the light weight (9.9 oz/280 g) means you`ll actually carry it around with you, greatly increasing the chance that you`ll get a great photo.
