The interchangeable design of OO spectrometers allows users to easily swap different slit sizes, which historically could only be done by sending them to the manufacturer. This makes it easier to find the most efficient configuration for your application. While there are benefits to decreasing the slit width, there are also drawbacks. The main benefit is that resolution is increased when the slit size decreases. This can be essential when precise measurements are needed. On the contrary, as the slit size decreases, light throughput also decreases leading to longer acquisition times. This would not be ideal for applications where speed is a factor. When changing the slit size from the given 25um one, it is also important to note that this can slightly skew wavleength calibration, but the affects would be minimal.
Overall, selecting the best slit size for an application is a balancing act of the required speed and resolution. It is recommended to purchase the slit kit if it is unclear which slit size would be best for an application.
