Andover陡(dou)邊長(chang)通濾光(guang)片(pian)
我們的陡(dou)峭(qiao)邊緣(yuan)長通(tong)濾光(guang)片(pian)采(cai)用磁(ci)控(kong)濺射(she)硬質氧化(hua)物塗(tu)層,可(ke)產(chan)生(sheng)深層抑(yi)制(zhi)並(bing)向高透(tou)射(she)率(lv)過(guo)渡(du)。塗(tu)層沈(chen)積(ji)在精密(mi)拋(pao)光(guang)的(de)熔(rong)融石(shi)英基(ji)體(ti)上,並(bing)且不使用任(ren)何(he)吸收性(xing)濾光(guang)玻(bo)璃(li),因此適(shi)合(he)高(gao)溫(wen)應(ying)用。它們提(ti)供(gong)三(san)種標(biao)準(zhun)尺寸(cun),並(bing)可(ke)根據要求提(ti)供(gong)定制(zhi)尺寸(cun)。
