The specifications are showed in the second page, column "Amplifier CEP HP/HR". Note that rounding errors may occur, so always check the results. x nm = 10,000,000 / x cm –1 y cm –1 = 10,000,000 / y nm. The area of my sample is equal to 4.7 cm x 6.7 cm. How can I calculate the Absorption coefficient from Absorbance? http://www.eit.com/instruments/UV-EB%20West%202009.pdf, http://oceanoptics.com/product/usb2000rad/, https://www.researchgate.net/publication/254217959_Ultraviolet_Lamp_Output_Measurement_A_Concise_Derivation_of_the_Keitz_Equation. If so, you can't determine the UV power from it - you will need a radiometer because lamp efficiency varies with wavelength. How? If you knew the formula, that would be very helpful. This information is critical for Fluence (J/cm2) estimation. 10 N-m to joule = 10 joule. J to zettawatthour Rightly so, within short space of time the UV light output decreases markedly. Start Give me some details of your experiment please? where “I” is current in Amp; and N is the number of photons arriving in a beam with coulomb (C) charge (Q) onto a given surface area. 20 minute te Sunlamp MED/minute 0.15 MED/minute 0.2 MED/minute 0.16 MED/minute 0.17 MED/minute Even the top quality lamp would only operate at around 35% capacity. Enter the value (for example, “15”) into the left, Alternatively, you can enter the value into the right. J to cheval vapeur heure. Use this page to learn how to convert between joules and millijoules. I am using UVA LED for my work and cant seem to figure out how to calculate the total UV dose (mj/cm2) when a surface is exposed to UV light for 1 hour. i�~.�3�uAq &��"٧�ڄ� T_Rz���l*L��'���݄��~�^�W7_�,�!hR��K F_QH��+ݜ���=ƙ�W���|"4 ��,�� -�Ѫ�%E�Q(H�����YFGcƶ� eTڌ�Zr���@f��4�R���pR�OQ'��|c,�-��'�L%-�Nf�+���W�$=��4Eб�r�B���˓] ȩ�0�.�E���Y�b��n[�{&�V����M����o�W�P��|i����De�MB���淏�O�*İ8v{=�)e�텚�$Es��N��W����X�ْK�(���k���2NskḦ́[!V(��c���cs�f�yhw?�1�v=n��=�L5���s\o~�V!���v1��R��XE�:uؔ0m]�//>��9H

If the wavelength is in a certain range (e.g., 400 nm - 600 nm), how can i calculate the energy does? or from equation I can directly calculate.

mJ I have a uv chamber 8 inches ×10 inches.. and has a 8w output bulb at 254 nm .. how long should the sterilization cycle be... if for sars cov-2 we need 250j per mter sq.

eg: 30W can be divided by say 3.. you get 10W of UVC. Type in unit Thanks. time. To calculate the flux from a mercury lamp reaching a point in space, you should use the Keitz equation. x nm = 10,000,000 / x cm –1 y cm –1 = 10,000,000 / y nm. Lamp output will drop with age, as mercury embeds onto the quartz tube and emission paste is sputtered off the filaments onto the tube. I would like to compare the UV dose of a UV lamp 365 nm, 6 mW/cm2 at a distance of 0.5 cm with the UV dose of a UV lamp 365 nm, 250 mW/cm2 at a distance of 19 cm. Square centimeter to Nanometer Calculator: Square centimeter (cm 2) :: Nanometer (nm) : Home

The answer is 0.001. Hi. Sohan Jheeta. This is my goal. Use this page to learn how to convert between kilogram centimeters and newton meters. Correction: In may answer above it should read "then the residence time of the beam on a spot is x divided by 2mm/sec," not the other way around. How much UV-light exposure time is required to disinfect a laminar flow hood? The Open University (UK) Hi Tariq. Is this enough information to calculate how much of a UV dose that the TrojanUVPhox can provide? Sohan Jheeta. J to kilopond meter On the plus side, it is possible to calculate J/m2 at 35% efficiency. Now the parameter of Speed of laser beam should be used to calculate the Maximum energy per pulse (in J/cm2) but with this strange units for the beam it is not straightforward for me how to do it? You can then work out the dosage by multiplying 15 by length of time of irradiation. So that is considered "new".

1 N-m to joule = 1 joule. Knowing the peak power of 12.8 kW, multiply 12.8 by the residence time to give you Jules of energy which can be divided further by the beam area to get J/cm^2 type of fluence information. First thing first, how long was the total ON time of the laser? Without the coating the output will drop to about 50% of the new value in a year (50% x 33% = 16.5% efficiency at 8760 hours). this makes much more sense. Hi, I need to perform the UV crosslinking of printed protein in microarray at 254nm and energy dose 1.25J/cm2. 20 N-m to joule = 20 joule. The unit has 10 bulbs each with a length of 84.3cm and 87 watts of power. as English units, currency, and other data. Wavenumber/Wavelength Converter. Alternatively, you may calculate this value by actinometry. 10-3, or in exponential notation, 1E-3. Mercury lamps often have fluctuating performance over the first hours, so manufacturers quote and measure output after a 100-hour burn-in. Because UV lamp of different wavelength 's are available. datasheet says 3.6W at 100 h. I think it means, after 100 hours of usage UVC would be 3.6W. C being a constant number and is equal to 1.602*10-19 C. at 100 hours say for example for a tube of 11W the datasheet says the UV-C output is 3.6W. I need to know the answers to the following questions: 1) Why do you want to work out the J/cm2? J or ›› Quick conversion chart of kg-cm to N-m. 1 kg-cm to N-m = 0.09807 N-m. 10 kg-cm to N-m = 0.98067 N-m. 20 kg-cm to N-m = 1.96133 N-m. 30 kg-cm to N-m = 2.942 N-m. 40 kg-cm to N-m = 3.92266 N-m >> J to terawatthour If exposure time is 900 seconds and distance from surface is 447cm, do you know how I might be able to calculate dosage (J/cm2)? 2) How far is the lamp from the target you are trying to irradiate? You also need to know how to workout dosage (J/M2) , is as follows: in 1s the energy delivered is 8.235 x 10-16 J/m2 (ie dosage), in 2s the energy delive. << We assume you are converting between joule and millijoule. The upgrade is an additional dispersive element introduced into the cavity to locally increase the peak pulse power.

Generally your operational manual should tell you the operational peak level that you should use. Tariq, there is information missing - what is the size of your beam spot? The UV Activity Phase of the Recurrent Nova T CRB. J to meter kilogram-force 2) from your technical manual I need to know either "spot" radius/diameter of the beam on the target/surface and/or how far is the source/lamp from the target/surface?
