Đặc trưng

• By combining two cylindrical lenses with different refractive index wavelength dispersion into a single lens, thin lines close to the theoretical limit can be created.
• Cylindrical plano-convex lenses (CLB-P) are recommended if you are concerned about color blurring or line blur.
• It is designed to reduce defocus in the entire range of visible light.
• Since the direction of the condensing line is parallel to the outer diameter side (B), optical adjustment is easy.
• It can be used as a substitute for a slit in a spectrometer.
• A cylindrical lens holder (CHA) is available for securing the acromatic cylinder lens.
• * The acromatic cylinder lens has a direction that allows parallel light to enter.
• * This function allows parallel light to enter from the side of the face with a small radius of curvature (the face pointed to by the arrow).
• * When parallel light is applied from the opposite side, the condensing line becomes thicker.
• * In the bus direction (B direction), there is no effect of the achromatic lens, no characteristic to reduce aberration, and no ability to collect light.
• * The light from the ray beam is incident on the achromatic cylinder lens and does not become parallel light.
• * Diverges in the bus direction (B direction).
• * In order to focus the light on a narrow line, it is necessary to allow high quality parallel light to enter the lens.
