After rigorous analysis and testing of various types of eyepieces using premium telescopes, the engineers at Takahashi have determined that the Plossl design is the best.
The TPL series uses highly refractive, low-dispersion glass and has an optical design that allows for outstanding image quality, with chromatic aberration at the center about half that of the Abbe series and about two-thirds that of the LE series eyepieces.
The image quality is extremely sharp from the center of the field of view to about half of the field of view. Although the star image quality degrades out toward the periphery, it is of high quality for visual observation, allowing the observer to focus on the center of the field of view.
The entire lens surface is coated with a multilayer coating that transmits more than 99% across the entire visible light range and has a high-quality matte finish, which prevents stray light from entering the lens.
The eye relief is approximately 70% of the focal length, and the apparent field of view is 48°.
Takahashi TPL-9 Plossl Eyepiece
TPL-9 Features
- Takahashi TPL eyepieces utilize highly refractive, low-dispersion glass for exceptional pinpoint and sharp quality.
- Chromatic aberration is minimized, with levels at about half of the Takahashi Abbe series and two-thirds of the LE series.
- Multilayer coatings cover the entire lens surface, ensuring a 99% transmission rate across the visible light spectrum.
- A matte finish on the eyepieces helps reduce stray light, enhancing contrast in views.
- The 9mm TPL-9 Plossl has a 48° field of view and around 6.3mm of eye relief.
Unmatched Sharp Quality without Breaking the Bank
The Takahashi TPL eyepieces consist of highly refractive and low-dispersion glass which result in excellent pinpoint and sharp contrast in views by minimizing chromatic aberration to half of what is present in the Takahashi Abbe eyepiece series and two thirds of the LE series. To further improve contrast, Takahashi has coated the eyepieces with multilayered coatings with a visible light 99% transmission rate and reduces stray light with a matte finish.
This configuration of the TPL eyepiece is a 9mmmm Plossl with a 48° field of view. The eye relief is approximately 6.3mm.
