DK480 1/2m 單色儀
DK480是一個(gè)與軟件結(jié)合的較好解決方案。三光柵塔臺(tái)容易控制，電動(dòng)控制狹縫寬度，和可供選擇的快速的電動(dòng)濾光輪。儀器可被設(shè)置為恒定的分辨率，自動(dòng)修改狹縫寬度，補(bǔ)償變化中的色散與波長，保持恒定的光譜帶寬。堅(jiān)固耐用，A級散熱設(shè)計(jì)，SP的光柵驅(qū)動(dòng)器使得可重復(fù)性和可靠性好，出廠前校準(zhǔn)。
產(chǎn)品特點(diǎn)：
通過RS232 或者 IEEE-488連接任何電腦.
電動(dòng)控制狹縫寬度.
三光柵塔臺(tái)能對大范圍波長進(jìn)行掃描，分光.
廠家預(yù)裝配單色儀和光譜儀.
