From Google AI-
The Oriel Newport 77218
is a precision fixed slit designed for use with Oriel monochromators
and spectrographs. It is the most economical choice when a single,
non-adjustable slit size is required for high accuracy and
repeatability.
- Slit Width: 120µm (or 0.12mm)
- Slit Height:
18mm total; however, the usable height is typically12mm when installed.
- Material/Design: Fixed onto a machined block designed to slide into a 77294 fixed slit holder.
- Compatibility: Works with Universal series instruments including the Cornerstone 130/130B, Cornerstone 260/260B, MS260i, and MS125 series monochromators and spectrographs.
- Accuracy: Offers superior repeatability compared to micrometer-adjustable versions.
