Without more information, as suggesting by the various comments, it's hard to be completely sure but, based on the information available, the format seems to be a very simple uncompressed vendor-specific 'raw' format with no specific identification or 'magic' numbers or tagged structure.
What follows is my best guess as to the format. Having a full file and a picture of the image it is thought to contain would confirm specific details either way.
The header appears to have the following format -
00000000: 00000800 // width of image (W) = 2048 pixels
00000004: 00000600 // height of image (H) = 1536 pixels
00000008: 0000000C // number of bytes per pixel (B) = 12 bytes
0000000C: 00006000 // number of bytes per row (T) = W * B, probably rounded up to multiple of 8 or 16
The suggested size of 2048x1536 does appear consistent with specifications from several digitail/usb microscopes that are available online.
The pixel data then follows for each row, with each pixel appearing to be stored as 3x 32-bit IEEE floating-point value (i.e. B = 12 bytes.) These three values being, presumably, R, G & B components in some order.
// 1st row
00000010: 3C8B50D4 3C8F6AF0 3C8974E5 // 1st pixel = 0.017006, 0.017507, 0.016779
Subsequent rows will appear
T bytes beyond the previous row.
// 2nd row (at 0x00000010 + 0x00006000)
// 3rd row (at 0x00000010 + 0x00006000 x 2)
// 4th row (at 0x00000010 + 0x00006000 x 3)
If correct, this would suggest your original file is relatively large at around 36MB.
