Plano Rod Lenses Rod Lens/Cylindrical Lens/Optical Cylindrical Lens For Medical Endoscopes
Rod Lenses for Rigid Endoscopes
Rod lens systems use special glass rods with optically finished ends, providing images with higher brightness, contrast and colour
reproduction than conventional lenses.
Commonly, rigid endoscopes have a series of high-resolution optical glass rod lenses. The endoscopes can be forward viewing (0
degrees) or angled (10–120 degrees) to allow visualization out of the axis of the telescope and increase the FOV by rotating the
instrument. The optical quality of lens-generated images of rigid endoscopes still surpasses that of the fiber-optic or digital
images produced by flexible scopes.
Why choose the sapphire?
1-Thinner and Stronger than Standard Glass Windows
2-Transmits Wavelengths Ranging From UV to Mid-Infrared
3-Features Extreme Surface Hardness and Chemical Resistance
Sapphire Windows are manufactured from single crystal sapphire, making them ideal for demanding applications (such as laser systems) because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. Sapphire is the second hardest crystal next to diamonds and, because of their structural strength, sapphire windows can be made much thinner than other common dielectric windows with improved transmittance. Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm.
