Figure 14:  Using Fixed Slits with MS257

 

 
 

 

 

Important tips for fixed slit installation:

 

 

  

The slit should always be inserted with its reflective side facing out (for example, towards the 
light source or the detector.) 

 

  

If the slit entrance is located on the right side of the slit holder, then the slit should be inserted 
with the notch located in the upper left corner. 

 

  

If the slit entrance is located on the left side of the slit holder, then the slit should be inserted 
with the notch located in the lower right corner (this will keep the reflective side facing out). 

 

  

The top portion of the figure above illustrates the correct slit insertion from the left side of the 
slit holder.
