Objectives 5-25X - 100X
Holmarc’s objectives features excellent optical characteristics under a wide spectrum of illumination conditions and provide various degrees of correction for the primary optical aberrations. These are colour corrected at 2 colors, with nominal spherical aberration correction. A variety of objectives are available with a wide range of cost and performance. Custom magnification objectives are available for your special application. |

Eyepieces 5-15X
Eyepieces, are available with different powers and varieties. Available magnification are 5X, 10X, 15X |
|
Kellners: It's a three element design and have a fairly wide field of view, up to 50°, and good eye relief, but need excellent internal coatings to minimize ghosting. They work best in long focal length telescopes and offer a good balance between performance and economy. |
 |
|
|
Plossl: A four- or five-element design offering excellent performance, especially in the 15- to 30-mm size range. Plossls provide good color correction and a moderate field of view (40° to 50°) |
 |
Ramsdens: Their apparent field of view is quite small, as little as 30°, and they don't perform well at focal ratios shorter than about f/9. |
 |
Huygenians: It offer good eye relief but suffer badly from spherical aberration and various other defects. |

Rubber Eye guards
These are designed for standard eyepieces and has eyecup style. It easily fits 1.25" (32mm) diameter eyepieces. Flexible rubber eyeguards reduce ambient light and glare reflections, while providing the viewer with comfort for maximum visual effectiveness. |

Condenser Lens System |
This condenser lens unit has replaceable front lens. It
helps to improve the illumination quality for different objectives.
These condenser lenses are designed with 8E design and
optimizes the chromatic and spherical aberrations.
The achromatic lenses collects the light to direct it at the
small area of the object which is to be examined. It makes the
object brighter (better contrast) and enable to control the angle at
which the illumination reaches the object. Condenser aperture
controls the area of specimen to be illuminated.
