DLPNIRNANOEVM: Lamp stability

BASAVARAJ AMOGI

Part Number: DLPNIRNANOEVM


Respected all,

This is in reference to the expected problem of lamp stability issues.

While taking a scans using DLP Nano device we have two options. One is keeping the lamp on continuously and the second is"on and off mode". Keeping the lamp continuously on will allows the user to avoid any lamp stability issues and reduce lamp wear caused by turning the lamps on and off, as well as the additional time needed to wait for the lamps to stabilize before executing a scan. My question is for how much time we can keep the lamp on without loosing lamp stability? Keeping lamp on continuously will increase the temperature. How exactly this tradeoff operates between the lamp on time and temperature? Apart from solving the lamp stability issues does "Keep lamp on" option has any other benefits?

Thank you,

Kind regards,

Basavaraj

    Hello Basavaraj,

    Allow us to look into this and we'll get back to you this week.

    Hi Basavaraj,

    The NIR evaluation module and supporting  software are designed to provide flexibility for evaluating optimum configuration for application. 

    "How exactly this trade-off operates between the lamp on time and temperature? Apart from solving the lamp stability issues does "Keep lamp on" option has any other benefits?"

    The lamp temperature vs on-time will depend on product design and environment (ambient temperature, airflow etc). In case of the EVM, I have used it for 5-10 min on time and performance has been consistent.  

    I suggest hat you run experiments to find optimum configuration for your use case.  You can capture system and detect tor temperature from the output scan file over time.

    regards,

    Vivek
