Singlets are available in a wide variety of shapes. Plano-convex and biconvex lenses have a positive focal length, plano-concave and biconcave lenses have a negative focal length. Meniscus (convex-concave) lenses may be either positive or negative and are used when very long focal lengths are required. Aspheric lenses have one aspherical surface and one spherical or plano surface. They are used principally as light condensers. Spherical ball lenses are ideal for fiber-to-fiber and diode laser-to-fiber coupling. Gradient-index (GRIN) lenses combine refraction at the surfaces with continuous refraction throughout the thickness of the optic.

Melles Griot offers a family of four distinct, high-performance telecentric lenses for use in machine vision, metrology, and precision gauging applications. All provide low optical distortion and a high degree of telecentricity for maximum, accurate image reproduction, particularly when viewing three-dimensional objects.

Most microscope objectives are optimized for the same object-to-image distance. This allows objectives to be interchanged without refocusing. Most Melles Griot objectives have an object-to-image distance of 195 mm because long focal lengths are required to maintain both the same image plane (150 mm from the mounting shoulder) and good image quality. All objectives are achromatic and have industry-standard microscope threads for cross compatibility.
The visible, infrared, and infinite-conjugate microscope objectives from Melles Griot are achromatic (i.e., color corrected at 656.3 nm and 486.1 nm). The RMS mounting thread (0.8 inch, 36 TPI) matches the industry standard making these objectives compatible with non- Melles Griot microscopes. Color coding makes identifying objective power easy when numerical markings cannot be seen. Visible objectives are antireflection coated for 400 to 700 nm; infrared objectives are antireflection coated for 1300 to 1500 nm.
