The emission was recorded by a fully computerized CCD-camera imaging system (Polychrome II, TILL Photonics) at 525 nm, using a 63x 1.0 NA objective (Zeiss W-Plan Apochromat VIS-IR) and applying 4x4 pixel binning.
Nikons new CFI SR HP Plan Apochromat Lambda S 100XC Sil objective and silicone immersion medium provide high resolution, long working distance imaging capability to support these needs.
Part of TMB's Signature Series, this 92-mm apochromat is a fast f/5.5 triplet-lens design, making for a stubby, ultra-compact tube assembly.

While not unique, its striking carbon-fiber tube certainly helps set this 80-mm f/7 apochromat apart.

STELLAR APO Stellarvue adds a new affordable 4-inch apochromat to its line of premium-quality refractors.
One way to reduce the problem of chromatic aberration to negligible levels--and to keep the tube length manageable in larger scopes--is to introduce a third glass element to the objective, producing a triplet, or apochromat. Alternatively, exotic substances such as fluorite may be substituted for one or more of the lens elements, resulting in an apochromatic doublet.
It's the only 90-millimeter apochromat made with a three-element objective, which offers a level of color correction not possible with two-element designs.
An excellent Apochromat objective lens with high NA (0.11) and low distortion has been specially designed for the iNEXIV series, providing crisp, clear images.
Advanced apochromat optical system uses ED (Extra-low Dispersion) glass, realising a contrast-rich, clearer field of view;
