What to know before you buy
This optical slit collection covers the MSE PRO LSXF series of adjustable slits and the LSLB series of precision spatial filters. An adjustable slit sets the width of an aperture, so you can limit the light entering a spectrometer, monochromator or detector, or trim a beam to a narrow line.
A spatial filter does a different job. It focuses a laser beam through a small pinhole to strip out spatial noise and leave a cleaner beam profile. Compare the LSLB1 spatial filter with the LSLB2 if you need beam cleanup ahead of imaging or interferometry.
The slit range runs from the LSXF1 models up to the LSXF4-5 adjustable optical slit. Within a series, versions such as the LSXF2-20 and the LSXF2-14 differ in size and aperture range, so check each product page for dimensions, adjustment method and mounting. Before you choose, note your beam size, wavelength and mount type and match them to the product data.
Frequently Asked Questions
How do I choose an optical slit for my setup?
Start with the aperture range you need and how the slit will mount in your system. The LSXF1, LSXF2, LSXF3 and LSXF4 series each have a product page with dimensions and adjustment details. Compare those against your beam size or spectrometer input before ordering.
What is the difference between an optical slit and a spatial filter?
An adjustable slit limits light along one axis to a set width, which is common at spectrometer inputs and for shaping a beam. A spatial filter, such as the LSLB2 precision spatial filter, focuses a laser through a pinhole to remove noise from the beam profile.
What details should I have ready before ordering?
Have the beam diameter or input aperture, the wavelength range and the mounting method in your current setup. With those, you can compare models such as the LSXF3-20 and the LSXF1-20 on their product pages, or send the details to us for a recommendation.
How do I order several optical slits for a lab or teaching setup?
For more than a few units, use the bulk order request form and list the model numbers and quantities. If you need a mix of slits and spatial filters for one project, the quote request page lets you put them on a single quote.
