Asahi Spectra 高性能濾光片,多種類(lèi)可選
日本Asahi Spectra始創(chuàng)于1970年,于日本東京成立。因其在離子輔助沉積 (IAD) 和離子束濺射 (IBS) 等真空沉積技術(shù)等技術(shù)的多年深造,使其具備了硬鍍膜、對(duì)環(huán)境(濕度、低溫或高溫、熱沖擊或真空)的出色耐久性和光譜穩(wěn)定性的出色能力。
日本Asahi Spectra的主營(yíng)產(chǎn)品分濾光片和光源儀器兩大類(lèi)。而其中,日本Asahi進(jìn)口濾波片,以其高性能,成本性?xún)r(jià)比高著稱(chēng)。在濾波片的類(lèi)型上主要分有短通濾光片,長(zhǎng)通濾光片,帶通濾光片,中性灰度鏡(又稱(chēng)為中灰密度鏡或者中性密度濾波片),超冷濾波片。其工作波段囊虧常用UV紫外波段,VIS可見(jiàn)光波段和IR紅外波段。濾波片的材質(zhì)以熔石英為主,尺寸分為兩種:φ25mm的圓片,50*50mm的方片,鏡片的厚度均為1mm。
Asahi帶通濾光片:
帶通濾光片通常用于傳輸明確范圍的光譜波段,同時(shí)抑制比傳輸波段的長(zhǎng)的波長(zhǎng)和更短的短波長(zhǎng)側(cè)。 日本Asahi Spectra的涂層設(shè)計(jì)基于多腔諧振器。 因此,其帶通濾光片在窄通 10nm 波段之外具有非常陡峭的斜率和非常高的衰減。

Asahi短通濾光片:
日本Asahi進(jìn)口濾波片的短通濾光片通常用于隔離范圍光譜區(qū)域。 Asahi濾光片的作用是在波段上傳輸比截止波長(zhǎng)短的波長(zhǎng)的能量,并阻擋比截止波長(zhǎng)更長(zhǎng)的波長(zhǎng)的能量透射。此外,通過(guò)與長(zhǎng)通濾波片一起使用,短通濾光片可用于自定義帶通濾波。 Asahi Spectra 提供多種波長(zhǎng)范圍廣的短通濾光片:紫外線(xiàn)、可見(jiàn)光或紅外線(xiàn)波長(zhǎng)。
