Features:
*Optimized for use with corrected optical systems featuring a 160mm tube length, for biological microscope applications.
*Adopts the industry-standard DIN 45mm focal length, with precisely coated optics for consistent, bright, and clear observations.
*Includes spring-loaded objectives at 40x, 60x, and 100x magnifications, offering effective protection against slide damage during specimen examination.
*The 100x objective is engineered with pine pitch to support the special design of the numerical aperture, enhancing fine detail resolution at high magnification.
*Engineered to minimize chromatic aberration, spherical aberration, and paraxial coma across two spectral bands for improved image accuracy and .
