特徴

• By making both sides concave, this lens can efficiently refract light in a small space and spread light widely.
• This function can be used to increase the area of illumination.
• A lens made by BK7 for the visible to near-infrared range.
• Three types of lenses with anti-reflection film are available in the visible, near-infrared and infrared ranges.
• It can be selected according to your specifications from the wide variety of subdivided by outer diameter size and focal length.
• * The concave lens cannot collect light or tie a real image by itself.
• * Use in combination with convex lenses.
• * Spherical biconcave lenses have chromatic aberration, and the focal length depends on the wavelength.
• * When a high-energy pulsed laser is used, the condensing point is connected to the optical path by the reflected light of the concave surface, and a spark may be generated.
• * When using with a pulsed laser, use a flat concave lens.
