徠卡 Leica物鏡透鏡

160多年以來，徠卡顯微系統始終為研究，工業和醫學領域的各種應用設計和制造優質物鏡。 徠卡光學設計師的創新能力，聯合徠卡精密光學工程師的經驗和專業知識，確保為顯微鏡提供優質的光學元件。 經由復雜的，先進生產過程所生產出的物鏡，保證優質圖像質量。

光學的單色像差和色差

在光學領域中主要有2類像差需要被修正的，單色像差和色差。常見的單色像差問題有：球差，像散，彗差，場曲和畸變。而色差可分為縱向和橫向。

分辨率可達20nm

我們的物鏡可做到像差化修正，并具備優質的光學效能，榮獲多個獎項。
世界各地，科學家們都依賴于徠卡20nm的光學分辨技術對最細微的細胞結構作可視化展現。

Leica Achromatic Lens

Leica achromats are powerful objectives for standard applications in the visual spectral range, offering field flatness up to 23 mm.

The absolute value of the focus differences between red wavelength and blue wavelength (2 colors) is ≤ 2x depth of field of the objective.

HI PLAN

HI  PLAN objectives feature good chromatic correction at two wavelengths  and flatness over the whole field of view. Even the edges of the image  are sharp and require no refocusing. HI PLAN objectives are designed for  visual fields up to 20 mm. Versions for phase contrast are available. Leica HI PLAN objectives offer good correction properties while being extremely reasonably priced.

N PLAN

The N PLAN objective class comprises further improved achromats with good field flatness up to 22 mm. N PLAN objectives are suitable for transmitted light andDIC, N PLAN PH for phase contrast. For incident light applications including differential interference contrast (DIC),  N PLAN EPI objectives are available. The N PLAN EPI BD can also be used  as a darkfield objective. The N PLAN EPI incident light objectives  feature excellent image contrast and safe working distances.

FL PLAN

FL PLAN objectives are modern universal objectives with outstanding chromatic correction and field flatness up to 23 mm.   State-of-the-art coating techniques give FL PLAN objectives high  transmission for fluorescence excitation. All contrasting methods are  possible. FL PLAN objectives are optimized for fluorescence, PH andDIC.
