SLSH-25-50P Planoconvex Lens

[Features]
· Sapphire crystals are transparent crystals that do not absorb visible light up to the infrared wavelength of 5 μm. Also, sapphire crystals feature extremely high hardness and are resistant to scratching. A single lens made of this sapphire crystal.
· Since sapphire crystal is extremely chemically stable, it is used for outdoor optical devices.
· Since there is no absorption (1.4 μm, 2.2 μm, 2.7 μm) due to water (OH radical), it can be used for lenses of near infrared spectrometers.
· Sapphire is completely harmless to the human body, allowing it to be used safely.
· Jewel sapphires are natural sapphire crystals which have been adulterated with metal ions such as iron and titanium.
· Artificial sapphire crystals are colorless and transparent.
· * The surface does not have antireflection film coating.
· * With loss due to surface reflection (7.7% per surface), the transmittance is approximately 86.5%.
