50W Halogen lamp permanently mounted to the side of the LP920 spectrometer, as a probe source for transient absorption measurements in the millisecond and second time range. The lamp is suitable for the spectral range above 300nm. The upper range is limited by the grating used.
The output of the halogen lamp is selected via a lever external to the LP920 sample chamber.
Note: This lamp is recommended for use in long lifetime measurements (milliseconds and higher). This lamp is required when using the Stop Flow Accessory (5-H).
