COMMODITY DESCRIPTION

A. 특  징  :

1) 파장 확장

FT- IR의 측정 영역은 다양한 광학 구성을 교체함으로써, 근적외선에서 원적외선까지

확장 가능. 

2) KRS- 5 windows

KRS- 5 재질은 DLATGS 검출기와 간섭계의 window로 사용. 또한 KRS- 5 재질은 KBr 재질에 비해 투과 율이 떨어져 타 제품에 비해 Signal- to- noise는 적은 경향이 있으나, 수분에 대한 함습률이 우수해 안 정적으로 Interferometer를 보호할 수 있음.

3) Step scan

Step scan FT- IR 분광기는 time- resolved 적외선 측정을 가능하게 함. 

Mid- IR 전 영역을 커버하고, high throughput을 유지하며 모든 진동수를 동시에 측정을 가능하게 함.

4) Quick start button

사용자가 측정 모드에서 PC에서의 setting없이 쉽고 빠르게 측정할 수 있는 시작 버튼임.

5) 자동 악세서리 인식 기능

악세서리를 기기의 시료실에 장착 하면, 자동으로 인식하여 data 수집에 있어서 

이전에 세팅된 parameter를 이용해 측정 가능. 

6) 빠른 스캔기능.

1초당 10회(10Hz/sec)이 가능하여 3차원분석이 가능.

7) Corner cube mirror

진동에 의한 광로의 흐트러짐을 real- time 방식으로 보정하여 안정적이고 재현성있는 Data 제공.

8) Resume switch

Main power off 상태에서 Light source에 필요전력의 50%를 공급하여 항상 Stand- by상태로 유지하여

별도의 안정화시간 없이 즉시 측정가능하며, Interferometer 내의 상대습도를 낮춤으로써 습기로부터

Beamsplitter를 보호.
