徠卡 Leica物鏡透鏡

160多年以來，徠卡顯微系統(tǒng)始終為研究，工業(yè)和醫(yī)學(xué)領(lǐng)域的各種應(yīng)用設(shè)計和制造優(yōu)質(zhì)物鏡。 徠卡光學(xué)設(shè)計師的創(chuàng)新能力，聯(lián)合徠卡精密光學(xué)工程師的經(jīng)驗和專業(yè)知識，確保為顯微鏡提供優(yōu)質(zhì)的光學(xué)元件。 經(jīng)由復(fù)雜的，生產(chǎn)過程所生產(chǎn)出的物鏡，保證優(yōu)質(zhì)圖像質(zhì)量。

光學(xué)的單色像差和色差

在光學(xué)領(lǐng)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(dá)20nm

我們的物鏡可做到像差化修正，并具備優(yōu)質(zhì)的光學(xué)效能，榮獲多個獎項。
世界各地，科學(xué)家們都依賴于徠卡20nm的光學(xué)分辨技術(shù)對最細(xì)微的細(xì)胞結(jié)構(gòu)作可視化展現(xiàn)。

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.
