Manufactured with premier grades of calcium fluoride and fused silica, these infinite-conjugate triplets are perfect for imaging applications utilizing a wide spectrum of wavelengths. Typical uses include fluorescence research in which the emitted light is in the visible and near infrared regions of the spectrum or in dual-pass systems in which the same lens is used to illuminate the excitation material as well as collect the emissions from it.

• Consistent focal length: 193 nm to 1000 nm

• Antireflection coatings available
