Absorptive Neutral Density (ND) Filters
An absorptive neutral density filter (ND Filter) is an optical element that uniformly reduces the intensity of light by absorbing light of a specific wavelength. It does not significantly change the color of light (i.e., remains “neutral”) and is widely used in photography, laser systems, spectral analysis, and other applications.

Aspheric Achromatic Lens
An achromatic lens is a lens that is designed to limit the effects of chromatic and spherical aberration,and is corrected to bring two wavelengths (typically red and blue) into focus on the same plane.

BK7 Glass Right Angle Prism
A right angle prism is a common optical prism with two right angled edges forming a 90° angle and a beveled (slanted) surface that serves as the reflecting or transmitting surface. It is widely used in optical systems for beam steering, imaging, beam combining/splitting, and other applications.
BK7 Light Pipe Prisms
The light pipe prism is an optical component used for guiding and distributing light, typically made of transparent materials such as glass, acrylic, or polycarbonate. Currently, Yutai Optics only manufactures light pipe prisms from optical glass. Its core function is to alter the light path through refraction, reflection, or total internal reflection (TIR), efficiently transmitting light from the source to the target area.

BK7 Optical Glass Wedge Prism
BK7 wedge prism is an optical component made of BK7 optical glass, featuring a wedge-shaped structure (two flat surfaces tilted at a slight angle). It is primarily used for beam deflection, collimation, or optical system alignment in the visible to near-infrared (NIR) wavelength.

CaF2 Fused Silica CaF2 Triplet Lenses
Triplet achromatic lenses offer excellent performance in chromatic and aberration correction and are suitable for high precision optical systems, but have higher cost, weight and assembly complexity. The choice needs to be weighed against the specific needs of the application.
Triplet achromatic lenses made of fused silica(SiO2) and calcium fluoride(CaF2) materials are used to correct chromatic aberration mainly through the different dispersion characteristics of these two materials.
